i like that there's a replacement in case i need one. not gonna lie though i was hoping you'd fix it instead of just buying a new and better amp . I'd probably change the title because its a bit misleading. maybe "how to replace your amp"
Hi buddy. Just returned to say thanks. Using your transistor fault finding technique, I was able to fix my subwoofer. I am sooooooo glad I didnt have to throw it out. I hate waste! Thx again.... thumbs up.

@Jameson Solomon i really appreciate your reply. I got to the site thru google and I'm trying it out now. I see it takes quite some time so I will get back to you later when my account password hopefully is recovered.
I was fixing many Klipsch subs for many years, the problem in the 95% of the units are the two IRF 740 mosfets in the power supply. I hear some technicians to say "the power supply can't be fixed" Power supply can be fixed if you buy the IRF 740 in a trusted company like Digikey. Ebay sellers sell counrfeit transistors. You need a desoldering gun for replace the bad transistors, I use a Hakko 808. Cheers.
I'm working on one of these power supplies right now and found a shorted mosfet. Q401. In your experience, does replacing the mosfet generally fix the problem or is there another issue that caused it to fail?
Thanks! I'm going to replace both of them. The leads on the old MOSFETS had some kind of metal spacer around some of the leads where they soldered to the PCB. Any clue what this is? Is Soldering in the replacements pretty straight forward?
I need a power supply for a Pro Media 5.1. It looks like the little standoff circuit board got super hot and the leg of one of the components burned open. I'm still looking for a source but haven't found one yet.
I been fixing Klipsch subs for many years. 90% of the problems are the short circuit in the mosfets IRF740. Is necesary to clean or remove the glue from the oscilator module because the glue become conductive. Is not commun to have problems in the amplificer or crossover. Cheers.
@@treadmillrepair754 very good analysis for the problem. Thanks a lot. Can you help me? How to identify the damaged irf740? And how to test if it is damaged? Thanks
Hey there... Great video very informative..i do have the sw450 klipsch sub. No power output after changing the fuse. May I ask if there is a compatible power supply to swap.
Your video has inspired me to go ahead and take a sledge hammer to my sub 10’s that failed with light use. I have two Yamaha yst 205’s that are still going strong after years of use. Japanese quality over the Chinese junk!
Do you know how many volts that power supply outputs? I'm wondering if it's 12 volts and would therefore work well in a vehicle. Edit: I just pulled the amp on my SW-8 and rewired the speaker wires to the speaker inputs on the back of the case to make it a passive subwoofer speaker. Then I used a class D amp from Amazon that cost all of $32 to power it. The Amazon listing is titled "ICQUANZX 2x50W +100W 2.1 Channel Subwoofer Amplifier Board with Treble and Bass Control, Dual TPA3116 Chip, DC 12-24V". Sounds great to my ears when powered with a 170W/20v laptop power supply. So anyone in this situation who wants to keep the sub might consider that route.
Quick question for you. Just got an RW-10 for free. Powers up just fine receive signal. No output. The volume knob on the side had a little bit of a hang up and doesn't feel right when turning it. I unplugged the volume control from the board and now I get some signal. Any ideas?
One question, pulling one of these open, the back won't give and open up. Any thoughts as to why and how to get it open? A friend of mine just purchased one and can't open it. Sadly he lives 6 hours away so I can't just go there and help.
Vintage Japanese built integrated amplifiers are just so much better made. They get warm and need proper air circulation because they are class AB amplifiers but, sound extremely natural and crisp. If it overheats because your weren't careful about ventilation, it will go into protection mode to prevent the output transistors from getting ruined. Love my vintage made in japan pioneer A9 solid state integrated amplifier and it's built like a piece of medical equipment compared to the bash plate amplifier. If I had that same or similar klipsch subwoofer and plate amp has faltered like yours, I would've put in a dayton audio plate amp in its place.
Hello, I have the same problem with my equipment. I need to buy that same module. Please, where would it be better to buy it on eBay? I couldn't find anything.
Dude sir, you should have measured across the capacitors on the new one to conclude they also had a short. You got me closer, but sadly that doesn't help :-(
Hello. I am looking for an electrical diagram (Service Manuals) for the Klipsch 112 SW subwoofer. Where to find it? As far as I know, Klipsch does not provide such information, even though their subwoofers, e.g. the 112 SW and R 112 SW models, are sold with defective amplifier modules. Best Regards SG
Thanks redonKiLaus for articulating this video so much better then when I made my UA-cam video a couple years ago, I was 100% winging it on the fly at the time. I found out the hard way at the time that trying to desolder the OEM Klipsch board was going to be tricky since it takes so much heat to remove the components with the risk of damaging the board traces. At that time there wasn't any online help for a fix other then sending the amp module off to be serviced, so after doing a bit of cross checking I found the power supply schematic to the Bash 300s made for a perfect direct replacement. Over two years on & the Bash 300s replacement power supply fix is still going strong (used the Klipsch Klipsch RW-12D for at least six hours this evening for the first leg of my complete nonstop Star Wars movie marathon to prepare myself for the upcoming Star Wars The Force Awakens).
+MrNightro I believe I saw your video when I was working on the sub a while back. I figured that I could use a generic BASH amp, and your vid confirmed that so I went ahead and ordered it. Definitely not worth fixing the old amp when new ones are so readily available. Thanks for watching!
Hi, Great video. I have a Klipsch XW-500D that died on me a few months back. My problem is trying to get inside the thing. I've removed all screws and nothing comes off. It's like the sub and the back-panel are both cemented to the enclosure. Am I going to need brute force to get in or am I missing something. I don't want to break the thing but I do want to get in and see what's wrong. In the video you showed that you removed all the screws then the next scene you had the panel off. Well I need those middle scenes on how you did that. lol
There is often a double sided sealing tape between the flange on the amp and the box, or the amp may have simply stuck to the box. The easiest way to get it off is by prying if you don't mind marring the box - if you want to preserve the finish, using a razor blade to cut the sealant may work well. Thanks for watching!
Had a chance to get inside and look around. Don't really know what I'm looking for as my amp seems to be the BASH 500 and I think yours is the BASH 300. I have some photos of it. I see one area around a capacitor and resistor and such where the yellow glue is dark brown now. If that is an indicator of something I'm in more trouble than just that because expanded around that area where the diodes are the glue is also dark brown. Is this junk now? Also the BASH 500S doesn't seem to be an "exact fit" for this one as there seems to be more connectors on the new one being sold that isn't on mine and other components as well from pictures I've seen. Below are pictures I've taken of my wounded amp. Also is there a fuse any where on this thing? I don't see the conventional fuse anywhere smg.photobucket.com/user/totalownership/media/IMG_3740.jpg.html smg.photobucket.com/user/totalownership/media/IMG_3739.jpg.html smg.photobucket.com/user/totalownership/media/IMG_3741.jpg.html
I need help downloading the service manual for klipsch R-112sw due to bad soldering. I lost the electrical connection of the capacitor C-19 Thanks🙏🙏🙏🙏 how can i connect it ???
I'm in the process of troubleshooting my amp as well. The information out there like this video is of no help. Theres plenty of videos out there to show you how to test components. A few people I read about claim the mosfets go bad and simply replace them. I dont accept that.Mine tested fine, You need to find out why the mosfetts blew in the first place if they did. I have ordered capacitor replacements from mouser. 2 larger capacitors 220uf 200wv have gone bad "high ESR".And the glue that they used back then becomes hard and brittle and starts to become conductive and causing shorts.
Yeah agreed. I had my 4.1 fail under warranty the first time 15+ years ago. They worked perfect ever since. I found the issue was when the two input 3.5mm touched / shorted. When I moved this happened but I haven't looked at it since having 2 kids. Now I want to fix it but need more info
So I have a Klipsch KSW10 and I recently heard a pop. It is still playing, had power but very very low volume and sounds distorted. I looked at the speaker itself seems to be ok, no noises from the cone and it feels solid. When I put it at full volume, sounds distorted and hardly any air from the port. Is it safe to say the amp is fried. Not sure if I should fix it or replace sub.
how do you get it to stop turning down when you turn the volume up mine seems to keep cutting Bass as the volume goes does it have some protecting thing in it or something silly I want to be able to blow it up
I am going to try and continue to fix this power supply, and if successful, will post a video on how to do it. I ordered a pack of IRF740 FETS, which I believe is the root cause of failure. This same power supply is also used in some Polk Audio subwoofers, as well as a few other brands besides Klipsch.
+Olasunkanmi Ogidan Hi- I was not able to fix the power supply due to the double sided PCB and several blown components that had no markings. The company over here "across the pond" from you for the BASH is Parts Express. They carry the BASH 300 and if you do an internet search, you can usually find a good discount coupon.
I did do that to double check a few things once the new one came in, but still couldn't pin down the issue for sure on the original so just swapped them out. Thanks for watching!
That's not a repair video ! Anyone can swap out the power section and wala " if you would have repaired and tested the old power supply, then it would have been a repair video even though you replaced it.. you should have kept on attempting to repair the old one , that is why I watch the video for ...
Whats the mean problem with klipsch subwoofers ? I see many people have problem with amps ? Now I have yamaha sw300 and think to replace it with Klipsch R-115SW what do you think ?
I have a Klipsch RW-10d subwoofer. Disconnected for 2-months during a kitchen/family room remodel. When I reconnected and turned it back on, the display was out. There is the typical "pop" when the woofer is turned off or on but no sound comes out when the stereo is on. Other than taking it to a repair shop, any suggestions
Did you get this fixed? Just brought out my sub from 3 year storage and it turn on and light on screen is on but no words on the display, no audio either
Same issue here, same sub. Left it unplugged for 3 or 4 years and sitting in a corner. Went to finally use it again and no display, no bass. No idea. You ever fix it?
The Bash 300W costs in excess of $250 (including tax, packaging and mailing charges). It is much more sensible to part out a blown Klip'shit chinaseum subwoofer and purchase a new, non-Klip'shit brand.
Hi, I have the same problem with 10d model with digital display same as yours. When I power up do display or light but when I turn off the power it blinks the display. I’m so interested where did you buy the power supply that will match with my 10d subwoofer.
Ever figure out the shorts on original psu? I just repaired one with two shorted power mosfets on the primary side (short video uploaded on my page) and was curious if maybe same issue!
Since that PSU is evidently a commodity part it would make a lot more sense to just obtain that from the PSU maker rather than cannibalising a brand new plate amp
I am getting a brief moment of power when I manipulate the power switch…I think it may just be the switch itself….don't think fuse is blown, but after removing back panel, I cannot see if any of the switch assembly is loose (all contained and glued to back panel).
Hi! I have a subwoofer SW-450. Prompt, where I can find an electric circuit for him to repair. The subwoofer doesn't work for a long time. Thank you for the answer
+Dmitry Shapoval It looks like you may be able to swap a BASH amplifier into that unit, but I haven't done it personally so it may or may not work. There isn't much information regarding that unit on the internet. Thanks for watching!
@@redonKiLaus allright! that's why if I replace it completely obviously it won't work anymore. how can i find the spare parts for that amplifier i caught fire but i can't find anything online.
Mine just exploded with blue flames and smoke when I plugged it in after two years. Emailed klipsch, they wanted photos. Sent photos and they said the circuit board looked ok and to contact someone else to have it repaired. It's in the trash and I'll never but klipsch again. The amps are made in China, buyer beware.
I'm glad I will be getting Q Acoustics 3020i speakers. Very nice solid bookshelf speakers and the sound quality cannot be beat for its price range. My Japan made built like a tank Pioneer A9 amplifier will provide the juice for them. Q Acoustics 3020i speakers are made in China but, just because they are of excellent quality. However, Bash amplifiers are junk and should be avoided. Dayton audio plate amps are better quality than Bash amps. Even a cheap lepai class D mini amp are better quality than Bash amps. If I had that Klipsch sub, I would've replaced it with a much better dayton audio plate amplifier after no avail with customer service.
hi, can you tell me if this Bash 300S can replace the plate in Klipsch SW 112 sub? the fuse is blowing all the time and after your video i think i would try buying that thing and replacing this..
I cannot seem to buy the 300 bash complete amp board like you did. Everyone is out of stock. Do you happen to have the part number for just the power supply? Maybe I can buy just that? Thanks
I looked for the supply separately, and could not find it back when I made this repair. Not sure if available now, or if the complete amp is even available, discontinued, or just in short supply due to world events. Thanks for watching!
greetings from texas , do you offer repair services ? i have a tannoy model ts300 that powers up but no sound. cant find anyone that works on it martin
I actually used to own a repair shop, but I do not work on any electronics besides my own these days...there are quite a few places both local and on the internet that may be able to fix your problem - just know that in some cases, a repair is either not possible or not cost effective vs. purchasing a new unit. Thanks for watching!
Wow, you got 10 years out of Klipsch computer speakers? That's impressive. My 2.1's didn't even make it to 2 years before the output transistors on the sub channel melted down.
This sub is a home theater unit, purchased as a standalone item years ago when I switched from a 10 to 12 inch sub in my theater. I don't have any experience with Klipsch computer speakers. Thanks for watching!
For us, the two mains stopped working, then shortly after, the sub also stopped working. One 25uf 50V capacitor for under $2.00 and a little solder work solved it for us. This guy finds/identifies the exact capacitor here at just under the 10min mark if you're interested: ua-cam.com/video/7mI9t_pmGR8/v-deo.html
man i had there best promedia setup......that amp blew 3 times.....lol i now run a MONSTER 64lb denon Avr 5800 $3,800(bought mint condition for $600) its 170 watts x7 at 0.05 thd to all 5.1 polk audio moniters and senheiser hd 599 cans......just insane....o yea running threw my creative xfi xtremusic card.....just mind blowing awesome...
Hey man, great videos and you don’t say “uuuuhhh” and “it’s like, like, like” every other word so that alone puts you in the top ten channels according to me.. my only wish is that you would zoom in a bit to the areas you’re addressing and maybe explain your methods such as multimeter settings and the respective functions a little more in depth. Thanks for taking the time to make and post the video, even if you laugh at my wishes and point and my lumpy head that’s okay at least you make good videos. Soooo like uhhhh like uhhhh thanks yeaaaa my bad!
Thanks for watching! I try to provide as much detail as possible in my videos, but when working by yourself it's difficult to perform the work and film in a timely manner.
I forgot to mention you can buy the BASH 300 unit from Parts Express. They are excellent to deal with and have prompt shipping. I used an on-line coupon to save even more. Too bad BASH doesn't offer the power supplies as a stand-alone item.
Klipch subwoofers are crap. I have the ksw10. Amp blew..I purchased a brand new amp from klipch. They provide a 60 warranty. Amp blew after 8 months. Avoid klipch. Both amps blew exactly the same spot. Funny thing is the fuse on both are good.
The sub I purchased had something like a 3 year warranty, but that was 10 or more years ago that it was purchased. I wouldn't be surprised if quality has fallen - like most formerly good brands (i.e. JBL, Harmon Kardon, etc) I'm sure they've moved production to cheaper sources. Thanks for watching!
Title of this video should be “How I pretended like I was going to diagnose and repair my Klipsch Sub, then decided to purchase parts that are close enough and put them in instead” total waste of time!
Your power supply or amp is likely dead, but I'm not familiar with that line of subwoofers so my only advice would be to take it to a qualified repair shop or to purchase a new unit if the repair cost outweighs that of a new sub. Sorry I can't be of more help, but thanks for watching!
look up a video of some common problems with your sub and if the ones you are having are the same with the common problems look up that common problem on youtube and see if there any repair videos its very easy to fix amps cuz most of them dont have little tiny things you have to use a microscope to replace
I got a sub 12 like this. However weird is, there appears to be power. and when the coax cable is slightly pulled, I get vibration from driver, but when conneceted blue light is on but no sound. again driver works, but its not sensing cable with sound only blue indicator light.
help please. have same rw12d and plays no sound anymore. Speaker is OK I have mesuered .it gets power becous display is workinv .Back inside at first look nothing is burned or smelled.what to do please.
Sounds like the amp/computer unit is getting power, but the speaker isn't. There's something wrong in the circuitry that outputs to the speaker - I've not dealt with that issue on one of these subs before, so I'm afraid I can't give any specific advice besides poking around to try to find bad components or continuity issues. Seeking professional help may well be necessary in your situation, but the repair diagnosis and cost may outweigh the cost of a new sub. I wish you luck with your endeavour, and thanks for watching!
Yes new one klipsch r12sw cost 250 euro. Is it even good as rw12d?last question:) Because to late it check technical for diagnose cost me between 50 and 70 euro
The R12SW is very highly rated, so I would assume it is just as good as the RW12D. 250 euro is a good price for one, too; here in the US it costs the equivalent of 325 euro. If a diagnosis costs over 50 euro, it is probably worth it to simply purchase a new one. If you feel like trying to fix the old one yourself once you have the new one, you don't have to worry about ruining the old one either, since you already have a replacement.
Pele19x89 hey I have a JBL Venue 10, and it works but for a short period when I give it proper signal. the internal amplifier doesn't change the LED to red. As a sign of a msofet overload? IDK. any thoughts
So I have a Klipsch sub-10 that is not playing any sounds. It powers on for I see the blue light indicating power, and If I place the cable wire next to a terminal on my receiver, I hear a humming sound from the sub. Is this a strong indicator that my internal amp is bad and all I need is the replacement amp listed above or should I run more test to find the exact issue? Update: one of my capacitors were bulging so I replaced it but didn't seem to fix it. I sent my board in to a guy who knows how to repair circuit boards so I will update when he fixes it. In the mean time, I bought this sub for 100 bucks to get me by. www.amazon.com/Polk-Audio-10-Inch-Powered-Subwoofer/dp/B0002KVQBA
I would try testing it with another receiver to ensure that your audio distribution system is not the problem, but otherwise, yes that sounds like the amp went bad. If you swap for one of the amps shown in the video, then note that you will lose the functionality of the built-in screen if your sub has one. Hope that helps, and thanks for watching!
So If I need to purchase a new amplifier plate, it appears the one you have in the video is bigger than my KSW-10. Since the circuit board is not square shaped but instead L-shaped, I don't think I can transfer the Bash 300 to my plate. The Bash 300 dimensions are also larger than my cutout hole so trying to fit a larger amp plate over a smaller hole means I'd have to shave off a lot of wood to get it to fit. Any recommendations? If I cut my sub to get the Bash 300 to fit, I don't think the seal would be that great. Would that affect the quality of the base sound greatly? cutout hole dimensions: 10.5" x 5" i65.tinypic.com/ouo68j.jpg i65.tinypic.com/ocvtf.jpg i68.tinypic.com/ridu8j.jpg
@@mbartlo24 What was the result of your investigation to fix your Sub-10? Your issue is same as mine on the Klipsch Sub-10. i'm on the fence between buying a new amp and trying to cut up my box to fit it, or just saying screw it and buying a new sub. The heartbreaking part will be tossing that sub-10 int the trash.
You dont think it´s a switching PSU? So where is the transformer? You obviously know far to much about electronics to NOT recognize an SMPS. Had a few drinks to overcome stage fright maybe? :) Thank you for the movie. I have a very similar amp myself, from a KSW-15. I wish I had found this movie earlier, cause it wasn´t easy to find the schematics and to get it fixed. The worst part, was realizing that the output stage is in fact class AB ... 300w RMS from a pair of IRF530/9530 (Pd = 88w @ 25c) .... I found that hard to believe. But then again... these amplifier dont last, do they? :) China in a nutshell .. selling 100w amplifiers with parts that can only handle 50w .. and that is if the parts are even genuine, which we all know, is not very often.
Like with all how to videos, this doesn't show what I need. He says "take off the torrent screws and remove the amp". Ok, except I do that and the amp is still stuck, it won't come out st all. Its fuckin stuck, and I look for help and all I see is "oh remove the screws, then take the amp out!" OK. Can't fuckin do it. Maybe something is extra fucked up wi tr h my amp. Fuck.
Not to downplay your work with this amplifier plate because you did a lot, but the truth is you didn't "repair" it, you just bought a new amp. This is just my two cents, so take it for what it's worth. The first time I watched this, I had all my parts laid out and ready to go. I already had a soldering gun and a decent amount of diodes, capacitors, resistors, transistors, the things needed for a cheap fix because I couldn't afford $300 for a new amp at the time. Of course, I'm pausing it every few mins to see what you're doing and trying to do the same, but then I get to the end, and it felt like someone kicked me in the nuts...🤣.lol. It's not your fault, but I do have a suggestion with the hope that no one else feels this way. You might want to add something to the video heading that says, "not the cheap fix," or something. Only because it still pops up in my search engine as the #1 plate amplifier repair video, and maybe that's because I've watched it before, who knows. However, after a year or two, I forget about it, then I click on it, and that's when I remember the feeling of my nuts hurting, and I storm off into UA-cam looking for my pain to go away. (Ok, maybe that's a bit much...lol.) I'm sure it pops up frequently for others too because the RW-8, 10, 12 series had as many or more problems than the one a few years ago, the R-110sw, R-112sw, and R-115sw amps that everyone was upset about. I really do appreciate all the information you did share and it's great for beginners who are learning how to test things, but it's not really a repair video as it is a swap amp-video. Just my two cents, which means my opinion isn't worth much....lol.
Me too with a Hakko. Just apply new solder, desolder, solder, desolder, and it should slide right out cleanly. It's just the 10+ year old solder doesn't flow well anymore, help it out a bit and it isn't a problem.
i like that there's a replacement in case i need one. not gonna lie though i was hoping you'd fix it instead of just buying a new and better amp . I'd probably change the title because its a bit misleading. maybe "how to replace your amp"
Hi buddy. Just returned to say thanks. Using your transistor fault finding technique, I was able to fix my subwoofer. I am sooooooo glad I didnt have to throw it out. I hate waste! Thx again.... thumbs up.

Video should be named, how to order new AMP instead of how to fix...
No lol. This video literally shows you how to troubleshoot a bad amp
I was fixing many Klipsch subs for many years, the problem in the 95% of the units are the two IRF 740 mosfets in the power supply.
I hear some technicians to say "the power supply can't be fixed"
Power supply can be fixed if you buy the IRF 740 in a trusted company like Digikey.
Ebay sellers sell counrfeit transistors.
You need a desoldering gun for replace the bad transistors, I use a Hakko 808.
Cheers.
I'm working on one of these power supplies right now and found a shorted mosfet. Q401. In your experience, does replacing the mosfet generally fix the problem or is there another issue that caused it to fail?
Jeremy Hi yes 99% of the times the problem is the mosfet only.
Chance both.
Cheers
Thanks! I'm going to replace both of them. The leads on the old MOSFETS had some kind of metal spacer around some of the leads where they soldered to the PCB. Any clue what this is? Is Soldering in the replacements pretty straight forward?
Is posible for you to send me a picture ?

I don't understand what are you talking about.
I need a power supply for a Pro Media 5.1. It looks like the little standoff circuit board got super hot and the leg of one of the components burned open. I'm still looking for a source but haven't found one yet.
This 7:40 minute "repair video" summed up in 5 words: "mail it off for repair" ...thanks, for nothing.

90% of the problems are the short circuit in the mosfets IRF740.

Is not commun to have problems in the amplificer or crossover.

Well is 2021
And my subwoofer ain't pounding no more. Now I'm looking for a way to fix it
Do you know how many volts that power supply outputs? I'm wondering if it's 12 volts and would therefore work well in a vehicle.
Edit: I just pulled the amp on my SW-8 and rewired the speaker wires to the speaker inputs on the back of the case to make it a passive subwoofer speaker. Then I used a class D amp from Amazon that cost all of $32 to power it. The Amazon listing is titled "ICQUANZX 2x50W +100W 2.1 Channel Subwoofer Amplifier Board with Treble and Bass Control, Dual TPA3116 Chip, DC 12-24V". Sounds great to my ears when powered with a 170W/20v laptop power supply. So anyone in this situation who wants to keep the sub might consider that route.
Quick question for you. Just got an RW-10 for free. Powers up just fine receive signal. No output. The volume knob on the side had a little bit of a hang up and doesn't feel right when turning it. I unplugged the volume control from the board and now I get some signal. Any ideas?

If I had that same or similar klipsch subwoofer and plate amp has faltered like yours, I would've put in a dayton audio plate amp in its place.
Hello, I have the same problem with my equipment. I need to buy that same module. Please, where would it be better to buy it on eBay? I couldn't find anything.
Great video!
I don't crank up my R-12sw but already after 2 months that have a bad rattle to them like it is blown. I'm Pissed!
turn your sub on all the way and see if it smells like coil you shouldent be able to smell anything if you sniff the port :
Dude sir, you should have measured across the capacitors on the new one to conclude they also had a short. You got me closer, but sadly that doesn't help :-(
Hello.
I am looking for an electrical diagram (Service Manuals) for the Klipsch 112 SW subwoofer.
Where to find it?
As far as I know, Klipsch does not provide such information, even though their subwoofers, e.g. the 112 SW and R 112 SW models, are sold with defective amplifier modules.
Best Regards
SG
This nearly same power supply is used in several models of plate type subwoofer:
Athena
Jamo
O Audio
HSU
Infinity
Polk
Klipsch
The svs amp is almost the same just trim the side 1/8
Jake Curl also looks like the non working amp in my Atlantic Technology 12"... I wish the video showed which component failed.
Thanks redonKiLaus for articulating this video so much better then when I made my UA-cam video a couple years ago, I was 100% winging it on the fly at the time. I found out the hard way at the time that trying to desolder the OEM Klipsch board was going to be tricky since it takes so much heat to remove the components with the risk of damaging the board traces. At that time there wasn't any online help for a fix other then sending the amp module off to be serviced, so after doing a bit of cross checking I found the power supply schematic to the Bash 300s made for a perfect direct replacement. Over two years on & the Bash 300s replacement power supply fix is still going strong (used the Klipsch Klipsch RW-12D for at least six hours this evening for the first leg of my complete nonstop Star Wars movie marathon to prepare myself for the upcoming Star Wars The Force Awakens).
+MrNightro I believe I saw your video when I was working on the sub a while back. I figured that I could use a generic BASH amp, and your vid confirmed that so I went ahead and ordered it. Definitely not worth fixing the old amp when new ones are so readily available. Thanks for watching!
My SW112 green LED light blinks. No sound. Any idea?
Hi, Great video. I have a Klipsch XW-500D that died on me a few months back. My problem is trying to get inside the thing. I've removed all screws and nothing comes off. It's like the sub and the back-panel are both cemented to the enclosure. Am I going to need brute force to get in or am I missing something. I don't want to break the thing but I do want to get in and see what's wrong. In the video you showed that you removed all the screws then the next scene you had the panel off. Well I need those middle scenes on how you did that. lol
There is often a double sided sealing tape between the flange on the amp and the box, or the amp may have simply stuck to the box. The easiest way to get it off is by prying if you don't mind marring the box - if you want to preserve the finish, using a razor blade to cut the sealant may work well. Thanks for watching!
Thanks so much for the reply. I'll try your methods to get inside. I'd rather have a marred and working amp than a pretty door stop. lol
Had a chance to get inside and look around. Don't really know what I'm looking for as my amp seems to be the BASH 500 and I think yours is the BASH 300. I have some photos of it. I see one area around a capacitor and resistor and such where the yellow glue is dark brown now. If that is an indicator of something I'm in more trouble than just that because expanded around that area where the diodes are the glue is also dark brown. Is this junk now? Also the BASH 500S doesn't seem to be an "exact fit" for this one as there seems to be more connectors on the new one being sold that isn't on mine and other components as well from pictures I've seen. Below are pictures I've taken of my wounded amp. Also is there a fuse any where on this thing? I don't see the conventional fuse anywhere

Thanks for your videos, they are very educational
I need help downloading the service manual for klipsch R-112sw
due to bad soldering. I lost the electrical connection of the capacitor C-19
Thanks🙏🙏🙏🙏
how can i connect it ???
I'm in the process of troubleshooting my amp as well. The information out there like this video is of no help. Theres plenty of videos out there to show you how to test components. A few people I read about claim the mosfets go bad and simply replace them. I dont accept that.Mine tested fine, You need to find out why the mosfetts blew in the first place if they did. I have ordered capacitor replacements from mouser. 2 larger capacitors 220uf 200wv have gone bad "high ESR".And the glue that they used back then becomes hard and brittle and starts to become conductive and causing shorts.
And this comment is of no help if you don't report back what success/failure you had... thanks a lot.
Yeah agreed. I had my 4.1 fail under warranty the first time 15+ years ago. They worked perfect ever since. I found the issue was when the two input 3.5mm touched / shorted. When I moved this happened but I haven't looked at it since having 2 kids. Now I want to fix it but need more info
I want to do this repair on a R112SW. Can you give me the value of the zener diode ZD6 ?
thanks!!
So I have a Klipsch KSW10 and I recently heard a pop. It is still playing, had power but very very low volume and sounds distorted. I looked at the speaker itself seems to be ok, no noises from the cone and it feels solid. When I put it at full volume, sounds distorted and hardly any air from the port. Is it safe to say the amp is fried. Not sure if I should fix it or replace sub.
I think I have the same scenario with the same speaker... How did you fix this problem sir...
I purchased it second hand
how do you get it to stop turning down when you turn the volume up mine seems to keep cutting Bass as the volume goes does it have some protecting thing in it or something silly I want to be able to blow it up
Hello. Can you just replace this amp and substitute it with another plate amp such as a Dayton 300w amp?
You certainly should be able to. Thanks for watching!
I am going to try and continue to fix this power supply, and if successful, will post a video on how to do it. I ordered a pack of IRF740 FETS, which I believe is the root cause of failure. This same power supply is also used in some Polk Audio subwoofers, as well as a few other brands besides Klipsch.
Hi +Jake Curl. Were you able to fix the power problem? I have the same problem. Am here is the UK and you cant find the Bash amplifier for replacement
+Olasunkanmi Ogidan Hi- I was not able to fix the power supply due to the double sided PCB and several blown components that had no markings. The company over here "across the pond" from you for the BASH is Parts Express. They carry the BASH 300 and if you do an internet search, you can usually find a good discount coupon.
+Olasunkanmi Ogidan www.parts-express.com/bash-300s-digital-subwoofer-plate-amplifier-300w-rms--300-750
Do you know what voltage the power supply outputs? Is it 12v?
gracias maestro solo quiero pedirle si puede subtitular los videos por favor gracias
I would have used the new power supply as a reference for troubleshooting the original one.
I did do that to double check a few things once the new one came in, but still couldn't pin down the issue for sure on the original so just swapped them out. Thanks for watching!
That's not a repair video ! Anyone can swap out the power section and wala " if you would have repaired and tested the old power supply, then it would have been a repair video even though you replaced it.. you should have kept on attempting to repair the old one , that is why I watch the video for ...
lol.....VOILA not "wala"
Whats the mean problem with klipsch subwoofers ? I see many people have problem with amps ? Now I have yamaha sw300 and think to replace it with Klipsch R-115SW what do you think ?
I have a Klipsch RW-10d subwoofer. Disconnected for 2-months during a kitchen/family room remodel. When I reconnected and turned it back on, the display was out. There is the typical "pop" when the woofer is turned off or on but no sound comes out when the stereo is on. Other than taking it to a repair shop, any suggestions
Did you get this fixed? Just brought out my sub from 3 year storage and it turn on and light on screen is on but no words on the display, no audio either
Same issue here, same sub. Left it unplugged for 3 or 4 years and sitting in a corner. Went to finally use it again and no display, no bass. No idea. You ever fix it?
The Bash 300W costs in excess of $250 (including tax, packaging and mailing charges). It is much more sensible to part out a blown Klip'shit chinaseum subwoofer and purchase a new, non-Klip'shit brand.
hi Guys any idea how to repair the volume on energy subwoofer? I noticed i can turn it up however as i try to lower the volume it doesnt work ?
Hi,
I have the same problem with 10d model with digital display same as yours.
When I power up do display or light but when I turn off the power it blinks the display.
I’m so interested where did you buy the power supply that will match with my 10d subwoofer.
You don't. Klipsch sends them out if you call them. I did and they did.
Ever figure out the shorts on original psu? I just repaired one with two shorted power mosfets on the primary side (short video uploaded on my page) and was curious if maybe same issue!
Since that PSU is evidently a commodity part it would make a lot more sense to just obtain that from the PSU maker rather than cannibalising a brand new plate amp
If it were available from the OEM, that wouldn't be a bad idea at all. Thanks for watching!
Would you, or anyone reading this, know if there is and where there is a replacement power supply for the rw8?
I am getting a brief moment of power when I manipulate the power switch…I think it may just be the switch itself….don't think fuse is blown, but after removing back panel, I cannot see if any of the switch assembly is loose (all contained and glued to back panel).
Had the same thing happen it's the crossover a little hole in one of the black chip. have to replace cross over with a different one
Hi! I have a subwoofer SW-450. Prompt, where I can find an electric circuit for him to repair. The subwoofer doesn't work for a long time. Thank you for the answer
+Dmitry Shapoval It looks like you may be able to swap a BASH amplifier into that unit, but I haven't done it personally so it may or may not work. There isn't much information regarding that unit on the internet. Thanks for watching!
good morning. the display obviously won't work anymore? not honcapito where it is connected on the 300s thanks
Display works perfectly, as I just swapped power supply boards, control board and main plate are still original. Thanks for watching!
@@redonKiLaus allright! that's why if I replace it completely obviously it won't work anymore. how can i find the spare parts for that amplifier i caught fire but i can't find anything online.
@@djhairychest If the whole amp is smoked then you likely need to replace the whole amp, at which point you'd lose the screen and all.
Mine just exploded with blue flames and smoke when I plugged it in after two years. Emailed klipsch, they wanted photos. Sent photos and they said the circuit board looked ok and to contact someone else to have it repaired. It's in the trash and I'll never but klipsch again. The amps are made in China, buyer beware.
I'm glad I will be getting Q Acoustics 3020i speakers. Very nice solid bookshelf speakers and the sound quality cannot be beat for its price range. My Japan made built like a tank Pioneer A9 amplifier will provide the juice for them. Q Acoustics 3020i speakers are made in China but, just because they are of excellent quality. However, Bash amplifiers are junk and should be avoided. Dayton audio plate amps are better quality than Bash amps. Even a cheap lepai class D mini amp are better quality than Bash amps. If I had that Klipsch sub, I would've replaced it with a much better dayton audio plate amplifier after no avail with customer service.
hi, can you tell me if this Bash 300S can replace the plate in Klipsch SW 112 sub? the fuse is blowing all the time and after your video i think i would try buying that thing and replacing this..
The amp is this:
Amplifier Type BASH Digital Hybrid
Amplifier Power FTC Rated Power: 300 watts continuous @
How i can find service manual klipsch sw r120
I cannot seem to buy the 300 bash complete amp board like you did. Everyone is out of stock. Do you happen to have the part number for just the power supply? Maybe I can buy just that? Thanks
I looked for the supply separately, and could not find it back when I made this repair. Not sure if available now, or if the complete amp is even available, discontinued, or just in short supply due to world events. Thanks for watching!
@@redonKiLaus thanks for checking. I appreciate it.
How do you get the panel off after you unscrew it?
You only need to remove the screws around the perimeter. It pries off with a spudger to get it started. (I had trouble, too.)
You have to use some force, it's double sided taped in.
greetings from texas , do you offer repair services ? i have a tannoy model ts300 that powers up but no sound. cant find anyone that works on it

I actually used to own a repair shop, but I do not work on any electronics besides my own these days...there are quite a few places both local and on the internet that may be able to fix your problem - just know that in some cases, a repair is either not possible or not cost effective vs. purchasing a new unit. Thanks for watching!
Wow, you got 10 years out of Klipsch computer speakers? That's impressive. My 2.1's didn't even make it to 2 years before the output transistors on the sub channel melted down.
This sub is a home theater unit, purchased as a standalone item years ago when I switched from a 10 to 12 inch sub in my theater. I don't have any experience with Klipsch computer speakers.
Thanks for watching!

@@redonKiLaus Some 2.1 came with a THX rating
Hi.. Someone haver the eletric schematic of Klipsch SW 112? Tks
For us, the two mains stopped working, then shortly after, the sub also stopped working.
One 25uf 50V capacitor for under $2.00 and a little solder work solved it for us.
This guy finds/identifies the exact capacitor here at just under the 10min mark if you're interested:

Hey man, great videos and you don’t say “uuuuhhh” and “it’s like, like, like” every other word so that alone puts you in the top ten channels according to me.. my only wish is that you would zoom in a bit to the areas you’re addressing and maybe explain your methods such as multimeter settings and the respective functions a little more in depth. Thanks for taking the time to make and post the video, even if you laugh at my wishes and point and my lumpy head that’s okay at least you make good videos. Soooo like uhhhh like uhhhh thanks yeaaaa my bad!

I forgot to mention you can buy the BASH 300 unit from Parts Express. They are excellent to deal with and have prompt shipping. I used an on-line coupon to save even more. Too bad BASH doesn't offer the power supplies as a stand-alone item.

Klipch subwoofers are crap. I have the ksw10. Amp blew..I purchased a brand new amp from klipch. They provide a 60 warranty. Amp blew after 8 months. Avoid klipch. Both amps blew exactly the same spot. Funny thing is the fuse on both are good.
The sub I purchased had something like a 3 year warranty, but that was 10 or more years ago that it was purchased. I wouldn't be surprised if quality has fallen - like most formerly good brands (i.e. JBL, Harmon Kardon, etc) I'm sure they've moved production to cheaper sources. Thanks for watching!
Title of this video should be “How I pretended like I was going to diagnose and repair my Klipsch Sub, then decided to purchase parts that are close enough and put them in instead” total waste of time!
Hi.
i have celestion s10 active subwoofer. as soon i put new fuse it burn it. i am in the the Uk can you please help me . many thanks
Your power supply or amp is likely dead, but I'm not familiar with that line of subwoofers so my only advice would be to take it to a qualified repair shop or to purchase a new unit if the repair cost outweighs that of a new sub. Sorry I can't be of more help, but thanks for watching!
look up a video of some common problems with your sub and if the ones you are having are the same with the common problems look up that common problem on youtube and see if there any repair videos its very easy to fix amps cuz most of them dont have little tiny things you have to use a microscope to replace
Any one know how can I find r112 without box
I got a sub 12 like this. However weird is, there appears to be power. and when the coax cable is slightly pulled, I get vibration from driver, but when conneceted blue light
is on but no sound. again driver works, but its not sensing cable with sound only blue indicator light.
So has anyone been able to fix one of these yet?!?!?!?
help please.
have same rw12d and plays no sound anymore. Speaker is OK I have mesuered .it gets power becous display is workinv .Back inside at first look nothing is burned or smelled.what to do please.
Sounds like the amp/computer unit is getting power, but the speaker isn't. There's something wrong in the circuitry that outputs to the speaker - I've not dealt with that issue on one of these subs before, so I'm afraid I can't give any specific advice besides poking around to try to find bad components or continuity issues. Seeking professional help may well be necessary in your situation, but the repair diagnosis and cost may outweigh the cost of a new sub. I wish you luck with your endeavour, and thanks for watching!
Yes new one klipsch r12sw cost 250 euro. Is it even good as rw12d?last question:)
Because to late it check technical for diagnose cost me between 50 and 70 euro
The R12SW is very highly rated, so I would assume it is just as good as the RW12D. 250 euro is a good price for one, too; here in the US it costs the equivalent of 325 euro. If a diagnosis costs over 50 euro, it is probably worth it to simply purchase a new one. If you feel like trying to fix the old one yourself once you have the new one, you don't have to worry about ruining the old one either, since you already have a replacement.
+redonKiLaus you are the man! thanks of lot. so i will get new one and some day find someone that can fix old one cheaper and then sell it old one ;)
It's the crossover there is some thing wrong with it look for a little hole on one of the black chips is bad
I recommend check first primary & secondary mosfets in power supply, next replace both 470uf/200v capacitors :)
When no output or extremly low output form audio board check 3x 4,7uf.35v bipolar capacitors :)
Pele19x89 hey I have a JBL Venue 10, and it works but for a short period when I give it proper signal. the internal amplifier doesn't change the LED to red. As a sign of a msofet overload? IDK. any thoughts
where did you find the fuse at ? I've looked everywhere
Duh i was in a dark room lol these plate amps are junk !
So I have a Klipsch sub-10 that is not playing any sounds. It powers on for I see the blue light indicating power, and If I place the cable wire next to a terminal on my receiver, I hear a humming sound from the sub. Is this a strong indicator that my internal amp is bad and all I need is the replacement amp listed above or should I run more test to find the exact issue?
Update: one of my capacitors were bulging so I replaced it but didn't seem to fix it. I sent my board in to a guy who knows how to repair circuit boards so I will update when he fixes it. In the mean time, I bought this sub for 100 bucks to get me by.
www.amazon.com/Polk-Audio-10-Inch-Powered-Subwoofer/dp/B0002KVQBA
I would try testing it with another receiver to ensure that your audio distribution system is not the problem, but otherwise, yes that sounds like the amp went bad. If you swap for one of the amps shown in the video, then note that you will lose the functionality of the built-in screen if your sub has one. Hope that helps, and thanks for watching!
I don't think this exact bash model will work for my cutout dimensions on the back of my sub are 11.5" x 6"
So If I need to purchase a new amplifier plate, it appears the one you have in the video is bigger than my KSW-10. Since the circuit board is not square shaped but instead L-shaped, I don't think I can transfer the Bash 300 to my plate. The Bash 300 dimensions are also larger than my cutout hole so trying to fit a larger amp plate over a smaller hole means I'd have to shave off a lot of wood to get it to fit. Any recommendations? If I cut my sub to get the Bash 300 to fit, I don't think the seal would be that great. Would that affect the quality of the base sound greatly?
cutout hole dimensions: 10.5" x 5"

I have the same issue. What did you determine on yours?
@@mbartlo24 What was the result of your investigation to fix your Sub-10? Your issue is same as mine on the Klipsch Sub-10. i'm on the fence between buying a new amp and trying to cut up my box to fit it, or just saying screw it and buying a new sub. The heartbreaking part will be tossing that sub-10 int the trash.
Dude, don't you know sign language?! I can't hear it, my speakers are blown, duh! :P
Closed cations works! :)
You dont think it´s a switching PSU? So where is the transformer?
You obviously know far to much about electronics to NOT recognize an SMPS.
Had a few drinks to overcome stage fright maybe? :)
Thank you for the movie. I have a very similar amp myself, from a KSW-15. I wish I had found this movie earlier, cause it wasn´t easy to find the schematics and to get it fixed.
The worst part, was realizing that the output stage is in fact class AB ... 300w RMS from a pair of IRF530/9530 (Pd = 88w @ 25c) .... I found that hard to believe. But then again... these amplifier dont last, do they? :)
China in a nutshell .. selling 100w amplifiers with parts that can only handle 50w .. and that is if the parts are even genuine, which we all know, is not very often.
Like with all how to videos, this doesn't show what I need. He says "take off the torrent screws and remove the amp". Ok, except I do that and the amp is still stuck, it won't come out st all. Its fuckin stuck, and I look for help and all I see is "oh remove the screws, then take the amp out!" OK. Can't fuckin do it. Maybe something is extra fucked up wi tr h my amp. Fuck.
Reason it failed: Switching mode junk
I paid almost $600 for my Klipsch sub and it died within 2 years. I'll never buy another Klipsch product. GARBAGE!!!
Boooo. Why did you start the repair if can’t finish it? That’s was disappointing!
These crap pcb so hard to work they strip the copper..better throw not worth
This video should have been called how to buy a new plate amp.... Smh
Man what was the point of making a video if you didn't show any of your work and so we can listen to a talking shirt?
Don’t waste your time watching this vid. His suggestion was to buy a new power supply. I want my 7 minutes and 40 seconds back.
Not to downplay your work with this amplifier plate because you did a lot, but the truth is you didn't "repair" it, you just bought a new amp. This is just my two cents, so take it for what it's worth. The first time I watched this, I had all my parts laid out and ready to go. I already had a soldering gun and a decent amount of diodes, capacitors, resistors, transistors, the things needed for a cheap fix because I couldn't afford $300 for a new amp at the time. Of course, I'm pausing it every few mins to see what you're doing and trying to do the same, but then I get to the end, and it felt like someone kicked me in the nuts...🤣.lol. It's not your fault, but I do have a suggestion with the hope that no one else feels this way. You might want to add something to the video heading that says, "not the cheap fix," or something. Only because it still pops up in my search engine as the #1 plate amplifier repair video, and maybe that's because I've watched it before, who knows. However, after a year or two, I forget about it, then I click on it, and that's when I remember the feeling of my nuts hurting, and I storm off into UA-cam looking for my pain to go away. (Ok, maybe that's a bit much...lol.) I'm sure it pops up frequently for others too because the RW-8, 10, 12 series had as many or more problems than the one a few years ago, the R-110sw, R-112sw, and R-115sw amps that everyone was upset about. I really do appreciate all the information you did share and it's great for beginners who are learning how to test things, but it's not really a repair video as it is a swap amp-video. Just my two cents, which means my opinion isn't worth much....lol.
Thats not fixing but replacing
Another 7:40 minutes of my life gone😉
I use a JBC soldering station And got the IRF easy out
Me too with a Hakko. Just apply new solder, desolder, solder, desolder, and it should slide right out cleanly. It's just the 10+ year old solder doesn't flow well anymore, help it out a bit and it isn't a problem.
