- A video on the process i usually take to repair faulty or broken amplifiers! The video has some unfocused areas I'm sorry, we are getting better at recording videos and better videos are to come! Please Subscribe!! Stay tuned for future builds and repairs!
I like the toss into the air and flip from top to bottom. That’s text book electronics repair beginning step. I’ve never seen it done better. I commend you sir.
Thank you so much Eric, I appreciate you taking the time to watch my video!!
I have a tool very similar to yours, I use it to remove cotter pins, and to loosen rubber cooling hoses during disassembly. Great video.
It’s called a cotter pin extractor tool
thanks brother..no offense to the rest..but your step by step is more detailed and understanding then the rest I've watched..keep it up..and thank you
Nice job. The resistors are giving the right resistance! Impedance is not a static thing. Impedance is a specific of an AC circuit.
You may want to point out to viewers the fact that a relay can have "bad" contacts as well as an open coil. I believe those strips w/heat sink compound are not there to help transfer heat, but are electrical insulators. Solder wick w/flux would be safer to the pc board traces and much quicker as well. Regards P.S. the longer you apply heat to your solder joint, the more you risk overheating that new component, and damaging the board. Solder should flow and be done within a second or two.
You are completely correct!!! it was a new soldering iron, it was my first nice one and I've kept it at a lower temp to try and only do fine soldering and hopefully prolong its life! I'm a electrical engineer and do more fine point soldering on circuits! I blew this amp a little bit ago and it was sitting and i thought id repair it! If you are into audio you should check out my Ipad install in my car!
Wait a go zakk
I love Solder Wick as much as the next electronic technician, but, you have to keep in mind that Solder Wick can short circuit a charged capacitor to an integrated circuit, and....well, You just damaged the chip, and the board. I learned that the hard way on an NES game system, that I was working on for my brother. I messed up a chip that's discontinued. If you like to use solder wick, make sure that you keep it short, whilst desoldering.
This guy actually knew what he was talking about, you could tell by the terminology he used. The only thing I woulda done differently is grabbed the cutoff legs with a pliers first and yoinked em out before using the desoldering tool to clean the holes. I see now he did figure that out eventually :P
that's cool, I used to work at the midas on grand river
really enjoyed this mate, and just chilling listening to you talk whilst i randomly took apart a broken amp of my own which i'll try tomorrow. did anyone ever tell you that you sound like a young ryan gosling from certain films depending on what you're saying? and then sorta like ross from friends in a couple bits but definitely gosling!
Good job man. Very helpful. Thanks
Cool video ! Back in the day i did my fair share repairing alpine, Kenwood and Rockford Fosgate amps. We were just too hard on them running the amps down to 2 ohms.
Its crazy the way amps are now adays! Theyre like 1/2 ohm stable. Its ridiculous!
@@VinnyGjokaj you younger guys today have way better equipment to put in your car compared to the primal amps we ran back in the day. I used to be an installer for Leo's Stereo way back in the day and people spent a butt load just to make their car thump.
@@petroldevo9934 I believe it!! You should check out my other video, I replaced my headunit in my car with an Ipad Mini!
@@VinnyGjokaj ill check that out when i can.
I was hoping this would be one of the ones that helps me out a little more, it is really apparent that this one ( video) is more lost than i am, even 19 years ago. it does serve a purpose though man. i am sure it has helped other people in ways that you may not have intended. like, if yu don't know what you are doing do not work on some expensive stuff, pic some old cheap stuff. that's a big one
the metal draws heat away from the components, every and any way that heat can be dissipated is a GOOD thing. the MOSFETS are on the rails because they get hot AF, some amps are fan cooled, some are assisted by fans but all of them have heat sinks of some sort.
anyway my search is on. OH your amp got hot and popped after 4 years of abuse. it was probably a small amount over a long while. if you blew a sub that sudden change in ohm could do it, if the amp was constantly having to pull more from smaller wiring that could do it, it could have been sudden but probably not.
Good job bro, i have done plenty of those fixes a while back.
Greetings from Kosova.
Awesome video bro. I just opened my Absolute 2300 watt amp. That thing slams!!! But recently "popped" I opened it up and it looked to be just a capacitor blew. I ordered some to replace the 3 but it still doesn't turn on. Any suggestions? I'll be going back to it to look at the parts you replaced as well.
Okay I'm going in. Thanks for the inspiration.
probably shold have asked after i watched your vid. ty man
Tip for soldering, you have the tiny wire and the nice soldering iron, all u gotta do is heat it up for a few seconds before adding the solder i add solder between the tip and the connection bad, and then keep holding the soldering iron on for a few seconds after i stop adding solder and it wont look so dull, you have cold solder joints the solder is basically just sitting on top not really flowed into both the pad and the pin, i can tell by the lack of shine and the way it looks grey and how u took the soldering iron off immediately after adding solder you have to hold the soldering iron on for a few seconds after to let everything flow together to = temps
You are 1000 percent right 👍👍👍👍
Great video !
This would have been a 100% excellent video for anyone looking to get into DIY electronics... but man, 90% of the "video" was blurred. And that's a real bummer for this repair.
You did an great job identifying the issue, though.. For that, props!!
I really appreciate the kind words, and also the constructive criticism. I am totally a amateur video maker, hoping to get better. I will focus on making sure that my videos are clear through out. Thank you for the criticism.
Looking forward to your next one!!!
yo.. thanks for this video ...purchased a genysis d18 2800 momoblock ampthat did this same thing but i cant find the transistors... were did you get the ones you used
I always find it easier to use a regular iron to remove the lead first, and then you can use the solder sucker to remove just the solder. Nice video though.
Yeah i really should've had the iron at closer to 750 Degrees (F), Plus i just need to expand my arsenal of tools i hope to get a nice vacuum desoldering iron!
Nice I'm open my amp and if that's doesn't is there other video with different problems on the same brand amp hifonics because mine is 2600 watt but it should be a much different right?
Nice informational video!
Thank you for the kind words! This was a Amp that used to power two Orions in my car for 4 years! i bought it for $40. did the BIG 3 upgrade in my car, two batteries! Thing banged hard! but the sub blew and a speaker blew so i went down to 1 12" on a 1000Watt amp, and installed a Ipad Mini in the dash!
i believe i hit 143 or 147dB (somewhere in the 140s) on TermLab at a dB Drag Race once.
I have a question that I hope to get help with. Never doing any repair myself, the power rail caps melted off the board (05 clarion dpx11500) but amp worked up to that point, had a second battery and fuse between batteries blew causing it to run off back battery until melting point, would putting in rail caps backwards cause it to push voltage from power inputs instead of taking it in? I think maybe manufacturer of caps put indicators of negative backwards as I put them in same as old caps and remaining caps before changing them all and made sure polarity was correct by connector wires. Or could it be something else? I would try to send it to you but cant afford shipping international.
can you upload a video puting the clips into the transistor please! i dont even know how to put it back
Where do you order those resistors? I need to repair my old school RF 4 channel amp. I put 12V 4.5A current to it from a power converter to use inside my home. I know it's not quite the power supply it needs. It was working great after years of being in storage, then it smoked, still powers on but no sound. Any help would be appreciated
it helped me a lot...ty
great video
Yes I need help potentiometer. I cleaned it last night. I haven't had a chance to hook it back up. But it had a lot of static when you touch it one channel would cut off on. Or when I hit a hump in the road. one channel would cut off. and I would have to turn the potentiometer just a little to get it back on . so I cleaned it last night. with some contact cleaner. I will keep you posted. Thanks. love the channel. But I do have a other amp .that need repair as well it when up in smoke .
how do you fix a gain on car amp everytime my bass hits my knob moves and causes it to go into protection after the amp gets warm
That was one heavy duty hook pick. I thought you were popping out components at first, LOL.
Haha yeah i sorted get my tools from all over!! Im a sub contractor and have collected all sorts of tools that I've repurposed for my engineering aspects! Its all good, can't beat FREE tools!
That a cotter pin Removing tool
I had the same Hifonics amp I like to know how do you get the part number for the resistors and transistors
I originally thought one of my channels blew on my amp. Did a ton of research on forums before realizing I'm an idiot for not thoroughly checking over external possibilities. While I was reading through various old threads I came across a car audio tech speaking with a layman. He insisted that the amp be brought in to a shop and professionally have the power drained out of it. Apparently they can hold lethal amounts of charge for months after disconnect. Is this an issue you've heard of before? It's got me nervous if I do ever have to access the inside
I've got a amp blowing fuses. Do you think this is probably due to the output transistors?
Vinny, can you tell me where to get the repair parts? I have a BRX1600 which is blown exactly the same way, in the same exact spot as in this video? Thanks!
I have a power acoustics 3000 watt class d amp keeps going in protection mode. I believe it's the same situation Ur fixing now. can u fix it
How much well u change too fix my AMP and can you put fan on it if possible
I’ve got a clip that covers the paste. What kind of glue can I use? It looks like a blue glue. I was going to sell the amp but I heard something rattling around so I had to remove the bottom cover. Is there something you can recommend?
Nice repair! I have trouble with shaky hands and poor vision. I wish I was able to do that.
I bet you can! It just takes a little practice honestly!!
+Vinny Gjokaj I was better yrs ago. i ruined a game console trying to hack it, but that chip was really really shall
I was the sameway!! I've broken so many consoles and electronics trying to fix them!! Last few years I've finally been able to fix more then I break!!
The chip to hack it was like 1.5mm with 20 legs lol for Nintendo Wii
Who left the nitrous on? IDC that was fun and I dig this dude
Thanks for the awesome vid. I have a 2 channel Zeus zx7500 and on one channel the music sound distorted. I opened it up and everything looks good. Nothing burnt. Any advice on what to look for?
Any capacitors that are blown? they using capacitors for all sorts of signal conditioning and if one is broken it can really throw off your amplifier.
Vinny Gjokaj Nah they all look good. No swelling on them no burnt marks. I guess i will have to take out the multimeter and take forever to trigger down the fault.
Hey man I got a Hifonics zeus 1200.1d amp i use to power my sa-12. I thought i blew the sub so i bought another one. I installed the new sub and its still making the same sound as the old sub (i thought was blown). Its like a horrible sounding bass frequency and sounds like the subs broke. What would cause the amp to give a bad output signal or whatever the problem may be?
Finally found the video I've been looking for!.. but you need to fire your camera man lol... I'm subscribing
Lmfaooooo thanks so much for watching my video Warwick!
I got the hifonics 2000w 25th anniversary edition and it was good but then the protection light came on and now it is stuck in protect mode, how can I fix? With no speakers plugged in just remote 12v and ground it is in protect mode. I'm going nuts someone help! Is there a reset to trick the board? Idk what to do anymore about to buy a new one but want to try to fix it just incase
I have this same amp which has a bad power supply because the N channel mosfets burnt. i cant find a pic online with the gate resisters anywhere. i just need a close up pic of your amp fets closest to the power / ground wire if you could do that for me. also have a hifonics 1206.1D and 2100.1D both blown i have to fix as well.
+Bain McCartney Yeah i can do that no problem!! Do you want one of just the Mosfets? Or do you have any other things that burned that you could use a pic of?
+Bain McCartney Okay i can do that!
The gold band on a resistor doesn't show orientation it just means tolerance (gold = 5%, Silver 10%), resistors can go in both directions.
my copper wound ring came loose how do I repair what's the name of it and how do you fix that
Yes hi quick question I have an audio 500/ 5 I wanted to know if you can help me where can I order transistors
Hell yea clandestine amp repair dude whooo
That was really kind of you Richi, I really appreciate you watching the video and leaving a kind comment. I hope you and your family had a wonderful Holiday Season!
I got a sundown scv 2000 d that needs fixing turns on but stays in protection mode
So that could mean a transistor/mosfet is bad, Capacitor could be blown out and shorted. Usually protect means there was a internal problem (usually short-circuit) somewhere in the amp. have you taken it apart?
I have a Brutus hifonics I think it's a 1750 mono, would you be willing to fix it if I paid you? How much would you charge? I'm having the same problem as you in this video power on no sound and no protection mode
Few tips, buy 50 ft roll of chem-wik by chemtronics for $18 on ebay, for removing excess solder on joints or bridged ones, it is made in america, secondly next time remove and clean the thermal pads and reapply new paste between the heat sink and pad! Clean all the Transistors then reapply new paste to them as well! If your pads are gone or shot, buy some 30mm wide Kapton tape, clean the surface it will be stuck to and apply it and cut it to size after it is applied to the heat sink! Make sure there are no bubbles and if there are screw holes use a pin or very small screw driver to poke the hole through for the screws, then apply thermal compound to the transistors, diodes etc before reassembly!
I am self taught, but have repaired amps that had completely shot, chewed and missing traces to working order! For that I use copper shielding tape and never wire! But some of my faves that I kept are Earthquake 400TX, Kenwood Excelon KAC-X1R Class D and Orion HCCA 225G4 modified with 10,000 Uf caps "1 Ohm stable Class A/B"! Some I sold or still have are Zeus 600 "API Brand", Oldschool Lanzar Optidrive 2300, Diamond Audio 300x1 class D, polk mono block, ppi's, one I did repairs for are sony's and audio pipes, MTX's and Crossfires! The way I look at it, I am helping the environment by refurbishing what would be waste!
Really? That cheap for wik, awesome! I will have to get me some!! I am slowly building up my tool collection, i would love to get a nice desoldering station, but im a college student on a tight budget!! Does kapton tape transfer heat well? is it thermally conductive? I use it on some of it on my boards for my job before they go into a metalizing chamber but i wasn't aware that it can conduct thermal energy well!
Vinny Gjokaj It resists thermal break down and is used to replace thermal pads, it does very well, some car amplifier distributors use it for a thermal tape, some subwoofers use only kapton based voice coils, it works well on amps! It prevents grounding and is very tough, it is sometimes used to protect areas of aboard when removing chips with high heat!
LuxorVan Yeah I've used it when i have to reflow BGA Chips to protect the surrounding board! Thanks for the advice! i appreciate it! Awesome talking to someone so knowledgeable
where did you order the mosfets from.
Vinny Gjokal i need you help I am watching your video of how to repair the amp hifonics but in my case I have a problem with the transistors Q84 Q85 Q86 and Q87 C2690A and A1220A are in short are two of each number and I have removed them assuming they were the same but they are different and I do not remember Where to put each one can help me with that plis ..........
Bro nobody has a channel that helps people figure out on their blown and before they send it out to get repaired and get charged hundreds of dollars if you continue what you're doing to help out I'm sure you will get a lot of subscribers I am one of them I will be subscribing at the moment please don't let me down
I swear thats all i want Louie, Thats how i got into electrical engineering, just trying to fix my broken electronics!! I do fix amps as i get them! I will post videos, hope you have a great holiday season!
Man U really know how to repair everything last time I came over u mad a wireless Xbox
+The destroyer 56 Yeah i love getting to know how things works!
I mightve just fried my amp .. my O gauge wire pinched against metal and my amp smoked all the way home .. im pissed its a 4000k BE elite hifonics .. can you repair it ?
good job bro.
Thank you for the kind words.
Hey, just gonna pick your brain a bit. I have a Lanzer 292N 5000W amp. I hooked up my pulse generator and accidently shot 60V into the input (Input sensitivity is .1 to 4 volts) and fried a resistor. Its a bit of a jump to ask, but any guesses on the resistor that I might of fried? I have pictures that I could email you if that would help at all. Thanks in advance.
I have an older clarion apx150001, had it in a vehicle with a second battery on 4 10s, fuse between back battery and front battery blew so it ran a few minutes off back battery before shutting off but after it did I noticed some rattling around in it, was some of those transistors you said would dome up, it melted them off the board, replaced them and now it powers on but arcs out and blows fuses and draws a very high current while melting a 0 gauge power wire. I see the Spartans shirt, are you in Michigan perhaps? I could pay yout to fix it, it was a monster when working and would like it fixed. get with me and I'll give you my contact info and most Likely business as well.
Anyone know where I can have an amp repaired.
Can u upload the circuit board power list transistors and output transistors please help thanks
Now I see what an Spartan education get you. Apparently no where.Go Blue
Maybe soo.... but i did turn down their offer. With job offers from MIT LL, Apple, ETC ive been doing alright!
My kicker amp keeps going to protection mode then flashes to green back an forth it's a 1200,1 any answers
he makes it look easy. I have the same amplifier and can't find what part needs to be replaced. It all looks good but just doesn't work.
+James Munro If you want to send me a picture of the inside of the amp i can look and see if i see any defects... unless if you wanted to send me your amp ill do a video on repairing yours!
where can I get the equipment from
Set the hakko iron temp 700f Use some good quality lead solder 60/40 and gel type flux.
That car amp has been out side in the cold and will have oxidation on it hence using flux when you repair it. When mosfets blow check diodes and resistors and winding for a short.
They sound like a jealous lot on here. Because you probably have bigger shoulders and they have and better looking most of them are. Good day.
i have a spl 3400 mono block im about to get into good vid
Let me know how it goes!
In impatience on my older US Acoustics 4065 I think 4 channel amp I shorted my channel 4 negative screw to the case with screw driver while in use and it made a crackle sound and started a loud screech out the speakers not sure if it one speaker or all... very upset can't afford new amp at moment, Any input whats up?
Hey Aaron, it sounds like you blew your MOSFET or could’ve possibly blew the AMPs fuses, have you checked your amps fuses?
@@VinnyGjokaj well I dodged a bullet somehow my pioneer headset to a dump at the exact moment?? I swapped in another head unit after bench testing the amp and it worked fine, kinda... The problem it has now is that on my bench and in the vehicle now it sounds distorted upon turning on for about 2 minutes the poof it clears up and sound great.... Like a component had to warm up? It doesn't feel warm to the touch it still feels ice cold where I live in Maine and it's winter now, but I've never had an amp affected by the cold... It works now this initial problem is kinda annoying but once going problem free. The only thing I've deciphered from Google searches is could maby possibly be causing it is old caps causing it it is a 20ish year old amp but is in excellent condition in my mother's mustang for 13ish years the pulled out and mothballed, it's never been pushed hard at all it was way overkill for her needs. I would love to repair it seems I've found US Acoustics is one of the "better" brands and a good brand true 65w x4 amp is not cheap...the closest one to mine is $230 now, they were made by Zed in the US just before mine so mine was made in Korea but is a quality unit so I'd like to keep it.
This dude here is my kinda guy. A bit different, and so laid back its like all natural xanax to me, yet I can see him going plum the fuck off too. An anomaly, and that's fuckin' cool. Way to go Vinny AllConsonants, you get an A++ and 40 gold stars as a human in my book!! ✌️
Thank you so much for your very very kind comment! I just try and be a good person to everyone around me! I feel like you are the same! I really appreciate you watching my video!
sir how to build output coil
what would cause a 12volts power supply to cut off power when you connect your amplifer?
It sounds like its going into Protection mode. Do you have any short circuits anywhere. Or have you opened the amp and checked that there are no blown transistors that are shorting out together
the only time I have seen npn transistors on the ps side of an amp...is from the 80's very early 90's amplifiers...this is odd to me
Made in China.
I’d love to send my amplifier to you to see if you could troubleshoot it and possibly fix it.
Are you located in Michigan?
I have a hifonics bxi 1206D and it turns on and into 3 secs of play it goes into protect any clues ? Thanks in advanced
Hey Brito, you could possibly have a blown transistor, when the amp powers up and the transistors heat up it could be causing the blown transistor to be shorted which would cause the amp to go into protect mode! can you take the amp apart and send me some pictures of the transistors!
Good job bro. I have the same amp with the same problem. I need help. Im not gonna try it myself. Do you do outside repairs? Im here in Michigan. Please get back to me.
Yeah of course, id love to help
Number? Are you in Michigan too?
Yes east Lansing Michigan
Thats far. Im closer to the Detroit area.
And then, the conversation stopped.
I have a brutus 2400 d brz and a few of my caps had pop how do I replace them
Usually you can just put some solder and go back and forth between the two contact points while holding the board upside down till the caps fall out! You should have the Soldering Iron set to a high temperature!
If the capacitors are blown can i simply replace them or will other components be bad too? I have a lanzar vibe the power was cut to it twice today and there was a loud thump threw the speakers (it always done this when turning the amp off) after the second time it would not turn back on i took the cover off and there are 2 caps blown possibly should change all 5. do you think any other components are bad now too?
Capacitors usually go bad for various reasons. It doesn't mean that anything else is broken also.. Its usually just the electrolytes in the Capacitor drying up and it makes them go bad! It dries up from heat most of the time.
ok thank you for the reply i will just replace the caps and hope it works again. Im hoping thats all it is I had it hooked up in my house using an old pc power supply and the amp was on for months so the heat from it probly did dry them up. thanks
Parker H did it work
Thankyou
hi do you work on rockford fosgate power amplifier i have a t1500bd that power on but it hads no output sound can you help me your can you fix it for me I pay $$$ let me know thank you
Is the amplifier this entire board? (I'm an amateur) I got speakers that need repair, they just started to loose energy and become weak. Just shy of the 5 year warranty (of course)
Yeah the amplifier is the board! And it’s cool you’re a amateur! Learning electronics is a awesome thing to do!!

Would you be able to snap a picture of the transistor? I could send you the part number and even a link where to get them!

i fried my Pinear AMP today HAD IT ON FULL BLAST FOR HOURS. smelt some burning capacitors. have to open mine and see what s what?
From what you’re saying it’s more then likely the power line on the board frying from the large amounts off current draw or the transistor(mosfet) blew from not being able to dissipate the heat. From the burning smell it’s probably the transistors which would rather be easy to fix, just put in new ones. Capacitors in these amps are used for two things, 1 filtering of the noises so you only output the music and not annoying buzzing sound, 2 stored power for when large amount of current is needed. So I’m really doubtful that it’s broken capacitors. When capacitors die it’s obvious because they’re usually bulged out at the top

Does it mean your amp dont work if its on protection mode ?
Hey Truejey, Not necessarily but more then likely, When it goes into protection mode its typically do to a short. If you have a blown transistor, like I did, and something shorts it will trip the protection. take it apart and take a decent picture and email it to me and I will give it a once over!

L.T. Lee Thomas No worries man!! Hope you get it fixed!
+Vinny Gjokaj model number for resistors? please
There is no model number on them! They are 1/2watt 47 Ohm resistors!
Man, I done a trade for a POS Pioneer amp. I need to open it up n see if it's blown. Thanks 4 the vid
Looks like an MB Quart board.
Dude good video wrong shirt go blue.
how do you know what transistor to get. the numbers on the top of the transistors F1010E
Well you can either get the same part number, Like you have right there is a power MOSFET. Or you can look for similar MOSFETs that have the same Vdss(drain to source brake down voltage), RDs(Static Drain-to-Source On-Resistance), and IDs(Drain-to-Source Leakage Current)
Vinny Gjokaj how do I figure that out?
Just search the model of the MOSFET.. but thats a fairly common one. Here is a 10 pack on ebay

have u ever worked on a Rockford bd 1000.1
No i haven't! But thats a awesome amp for sure!
Yea it was but now it turns on and just gets warm not shure what to do with it

what are those things called again the onse u replaced
+Hector gonzalez In this video i replace NPN & PNP mosfet transistors
Thank u mine is a trip cus when i smack it ..it comes back on it does it from time to time so im gona check what u did to mine thsnks
Hector gonzalez It could be that you have a broken solder join inside the amp or just your a broken RCA cable or something loose. This amp didnt make any sound till i replaced the transistors
Replaced the rca thinking the same and still does it im gona add a cap to see if that helps if not im gona ipen up and hope i have your eye
how do u replace caps on my vid i got a brx1116.1d and a few cap look poped
It would basically be the same way. Like i said in the video, if the capacitors have a cross on the top and it looks like its sticking out its blown and needs to be replaced. You should replace it with the same value because its the lowest risk. Depending on where in the circuit the capacitors are putting higher or lower values could create oscillations in the circuit and give you unwanted noise. It would basically be the same approach. You should just desolder the old one and mark where the strip is (The strip shows polarity, negative side) and just put in a new one and solder it up.
+Vinny Gjokaj yea three pop with the fish oil everywhere but it it still makes my subs bass just as hard i only noticed cuz it was leaking
ssg red its not fish oil lol! its actually liquid electrolyte, and yeah that doesn't sound to unrealistic. It could be Filter capacitors on the main power input. It usually there to filter unwanted frequencies that could create unwanted noise through out the amplifier at various stages. While it does still work it would be a good idea to replace those because you may start notice noise.
+Vinny Gjokaj yea it happend when i briged it well its a mono block but 2pos and 2neg but still a mono so i put the wires back to normal @1ohm and stop leaking but i still wana fix it if u look at my video do u think the amp gut would do its rated power 1100 rms in sides are a lil empty
Yeah that cap is blown! Trust me when i say you should replace it soon!! and im sure the amp could do 1100RMS at short bursts for not prolonged period of times.
Where did you find the parts that you needed?
The websites I get my electronic components are Digikey, Mouser, and Amazon! I hope you get yours fixed! Let me know! Facebook message me if you need any help
😎 thanks for your response 👍
I replaced the resistor that burnt up and still turning on in protect mode
SiL3nT. 0wNaGe usually if a resistor burned up that means a lot of current was being pulled. When a Transistor/Mosfet burns it can be shorted or act like a short to ground. Have you seen anything that looks burned or melted inside the amp?
Vinny Gjokaj no just that one tiny resistor. I read somewhere if one burns it’s best to replace the entire vertical row not sure how true that is but I only replaced the one. Everything else looks fine inside
