You should teach electronics for a living man. You keep it simple yet effective, and take away the intimidation. I feel a lot more confident after watching this. Thanks a bunch. Probably one of the best UA-cam videos I have ever seen. You have earned my respect and subscription.
Thank you so much for posting this. I'm a 60 year old man who has been interested in stereo gear since I was 14 in 1977! Now I'm retired and want to learn how to service my own vintage stereo gear and others'. You sir are knowledgeable and interesting to listen to. I will be subscribing to your channel for sure!
This information (and entire channel for that matter) is so important. As you say - a lot of master techs are calling it a day and it's getting harder and harder to find people to repair these things but with a little patience, practice, and research you can fix them. Thank you so much for adding your knowledge to the library!
Im a jack of all trades and and always trying to fix or repurpose electrical equipment so it can live on. You're very grounded and i can relate to you well. Thankyou. Often the power switch or cord are the culprit which is the easiest to diagnose with a continuity test. I think tests like that should be taught in high school. great vid
I Came across your channel 2-4-2024 and I'm Blown Away!!! You are unbelievabley so easy to understand, make all issuses simple and not convoluted! I've been working on equipment, amps, sound system etc. and self taught since the late 60's. Now I'm in my 70's and have made repairing vintage amps and speakers my hobby. I refuse to send my prize equip to anyone. I watch alot of UA-cam videos and can't understand how so many creators, make things so difficult to do or understand. I started to doubt myself until NOW. You have cleared the slate for me and I'm reassured of my knowledge, as it still is limited and I want to learn more. I have been told by many, oh you can't fix that. WRONG..... I can fix just about anything Vintage, from cars to homes. My problem is I was blinded twice my electrical failure. Now I'm Very Skitish around high voltage, not low volts. I want to Thank You, for your prespective outlook, Fix it don't toss it. Also about replacing the Electroliytic capacitors. This I have never done as I was told by an electrical contractor not to. I bought two Marantz model 19's New in 1972 and a 1090 in 74. I have cleaned and shrunk wrapped one 19 for 20 plus years, the other I had been using since i Bought it. The 1090 is missing the jumper from pre out to main in. I could not find anything to address this issue, without becoming so confused, i have cleaned and detox it, checked all circuitry to the best of my ability. Now, after watching you, I'm glad I haven;t tried to connect the Marantz 1090 with missing jumper. I will now buy all the Equipment, scopes, generators, etc at any cost. I don' like taking shortcuts, like I did unknownly. It's said, God helps the Blind and the Ignorant. I've been lucky. Thanks again, your new Follower, Pierre
Alright - this motivated me to fix my old technics SA-5050 PB. It is from the late 70s. I turned it on and it has some faint AM sound but nothing on FM or LP. It does show there is a signal. A lot to learn and fix!!
Thank you for making this video. I have learned so much from it. I'm old, and so is my stereo equipment. It was bought with hard-earned money many years ago, and I would like to hang onto it as long as I can. So before I get too emotional, thank you very much!
You sir are the wizard of vintage audio! I only wish you were my neighbor so I could learn some repair skills from you. I have a few vintage pieces I want to get repaired but am finding it very difficult to find a place that will not take advantage of me. I am more than happy to pay what is fair for quality repair. But finding someone like you that has the experience to do it right is getting hard to find. This is a great video by the way and has me wanting to dig in and repair my own but I do realize how intricate these things are. I can solder all day and organizing is no problem one step at a time. Finding the proper replacement parts that something else. Cheers.
I've got a 1968 Leak Stereo 70 amp. All original, even the smoothing caps! Still works but I'm a bit scared to use it until I've changed at least the caps that are subject to higher voltages. Electrolytics aren't blessed with a 52 year life expectancy! It's done extremely well but I'm not pushing my luck, damage prevention has to be foremost now. It's a great gutsy little amp and I want it to stay that way.
I think you are exactly correct in your thinking. Just because your amplifier has been fine for 52 years and beat the odds doesn't mean it will continue on for ever.

"30 years of experience in 30 minutes".. that's like saying I can grow a 30-year-old tree in your yard from a sapling if you give me 30 minutes. While I appreciate the sentiment, you and I both know it's simply not possible. You also have what we call in my business, "the curse of knowledge" in that you have so much knowledge that you don't realize just how much you take for granted regarding troubleshooting and knowing where to look, what to look for, how to test a component, and what values are good and bad. Unless someone wants to start their own hobby fixing vintage radios, convincing Joe Schmoe that he can fix his Pioneer SX-1980 is a horrible and ridiculous idea. I love your enthusiasm... it's just not Realistic (pun intended).
Well said carlos. I am brand new to the hobby... my wife and I are looking at a Delmonico piece and she wants it to work. This guy has given me the hope needed to make the purchase and attempt the repair.
1. he flashed a Yamaha briefly, he has never shown a Yamaha before......cant wait to see it. I have all the tools except a solder sucker, I plan on replacing my capacitors 1 by one so I can keep track of things. The section on Oscilliscope was great. I have a 2 channel, but I do not know how to use it at an advanced level. basic measurements ok, I have some old electronics boards that I plan to practice soldering on as well as taking test measurements. This was a great video. It addressed some of my biggest concerns like how to choose a capacitor.
Loved the video . Have to argue with you on one thing though ! DeSolder machine (Haako) is a must !! I was a tech for over ten years before I got one . I kick myself for everyday I went without it !!!!
This is the best instructional I have seen yet! I am a crane mechanic. I can read schematics and specialize in 24 volt German built cranes. I understand most electronics DC and some AC. I recently bought a Sansui 5500, the same receiver my father had and want to recreate his rig as a tribute to him. I loved the way it sounded with Pioneer CS99A speakers! Anyway I can't get the info from hifiengine. It's not accepting new members. Can you or anyone please help?! I need a service manual and schematics for a Sansui 5500. I bought it on eBay in working condition and it was well packaged. However when it arrived it won't power up. It immediately blows the 5 amp fuse in the back. Thanks for the great video!!!!
Hi Chris, I want to start off by letting you know how much I appreciate all of your YT work. Based on your recommendation's here I purchased a used Tek 475, variac, power supply and a couple of DMM's. Also purchased a new Uni-t utg962e DDS Function generator, and I'm building a simple Dim bulb now. I have a very limited background in electronic's - so I have a basic understanding of components, issues and test equipment. What I could use now is some basic instruction in connecting and using the function generator to troubleshoot some vintage receivers? And help using a "1 block at a time" instruction in schematic reading and applying that to a couple of 70's Pioneer and Kenwood receivers and amplifiers. Thank you and Best Regards, Jack P.S. I did email you - but noticed a comment that said your email was full.
Hey, Jack. Thanks for your kind words. Sorry about the email it really gets a little crazy sometimes. No way to read/respond to many of them. I'd never restore anything or get video's up on UA-cam. It's great that you got some test gear. Do some searches here on UA-cam for the information that you are looking for. A lot of good stuff here but sometimes it's hard to find exactly what you are looking for. Good Luck! It's a fun hobby.
if the gear is over 30yo, i replace all electrolytics. they are cheap and easy to replace. why risk it? i have been restoring vintage audio since late 70's and am too old to screw around. i also eliminate all ceramic caps as they are a huge source of noise. another component i always replace is composite resistors. i always use film resistors which are not a noise source. i also always use 1% resistors which allows for much easier balancing of the sides. i also like to shield signal wires as they also can introduce a lot of noise. if you do this yourself, the cost difference is not a big deal. it does take a lot more time, however. but when you are done, you will not believe your ears. when your gear is not fighting itself with unnecessary noise in the system, you end up with much more precise and detailed sound. your headroom will expand beyond what you thought possible and the music comes alive. i have taken very average vintage audio, rebuilt it and a/b tested against some of my customer's supper expensive new audiophile gear and blew them away every time. a well-tuned audio gear means you do not need 200W+ per channel to hear everything. you do not have to turn up the volume as much. it is tedious work and requires attention to detail, but it is not difficult.
Great overview, thanks. I am going to start repairing and upgrading a Bryston 2blp amplifier after new year's celebrations. This information will help.
enjoyed the video ! I am trying to get the balls to replacing the big electrolytic s in the power supply of my 1978 Nikko Alpha III power amp...the unit is in perfect, original operating shape now, so kind of a preemptive strike. Nothing in my electronics is newer than 1979 (except speakers) and it cranks. I really like the de-soldering gun you used, beats using braded or twisted wire I imagine !
Very interesting overview! And it really makes me want to get some broken equipment and try to fix it. As soon as the flea markets and stores can open again (due to our tiny pandemic problem) I'm going to get all the stuff I need :D. Thanks for the inspiration and encouragement! All the best
I always liked your style of explaining repairs. Just enough info that someone that knows what they are doing will be able to learn something new or get an idea of how to fix a unit they might have gave up on. In that spirit this video is great, but I don't think you should recommend, or even lightly imply, that someone that doesn't know how and doesn't know a tech should try and fix it themselves. Like you, I want this gear to survive and I wouldn't want people that don't have a clue to attempt a repair and further damage a unit to the point that it's no longer repairable by anyone! If they can't repair it and can't find someone to fix then maybe the best course of action is to sell it at a fair price given the condition. At least that way you are still giving that old unit a chance to bring someone joy again rather than end up in the trash heap. Other than that, great video!
Thanks for sharing your comments. We all think differently and that's okay. Vintage audio repair is not terribly difficult IMO but it's because of the way I think. I think most folks that have learned a skill in life can learn other's. Thanks again!
What a great round up on starting to work on vintage gear!! Thx a lot for this inspiring video! 2 questions on the tool set: would you recommend to use a Dim Bulb Tester when powering up a piece of vintage gear for the first time (after examining the inside) in case there is an accidental short? And/or would you recommend to use a variac for powering up vintage gear slowly when stored for a longer time? Thx a lot for sharing your experience and expertise!
I like your foresight comments towards the end of the video. Do you have any perspectives on regional climates and their effects on all this old stuff? Automobiles for example, rubber and plastics survive longer in the humid regions, steel and non ferrous metals however fair better in the arid southwest. How do these different climates effect electronics?
Mouser or digikey, parts for my vintage disk cutter.......even cryystal cutter head, parts are all available....You can 3d print the knobs..with the correct specs..
I don't even care for electrolytic caps, I have literally bags of tantalum from Kemet, from 0.1 uF to 470 - Bought them for peanuts, around 95, from a local supplier that had to close down - Before you jump into the comments, I've never had a fire or explosion, those things are so little that you can replace them with one rated for double the voltage... They have even lower ESR, they can handle all audio frequencies whereas electros increase the impedance as the frequency goes higher. They're also much more stable, the value doesn't drift with temperature, leakage is zero and, most importantly, they last more than what I expect to live, so...
Good stuff! Cheap and imprecisely manufactured small hex tools are the worst. They ruin a screw in no time. How well do the wrapped connections age in your experience?
Thanks! The wire wrapped connections seem to do fine. The issue is when you bend them to much. Then the wires will break but that's true for new wires also.
Hi Thank you for your channel. Great videos. What about tuners... video. AM FM. What involves, tools. that would be great. I have 4 old receivers, two of them the radio performs really bad. Regards from Argentina
My wife and I have been collecting mid/mod furniture, lamps, etc for about 10 years. We are looking at a Delmonico piece and I was/am reluctant to buy. It lights up, when "radio" button is pushed, there is sound (static only) but the tuner knob/guts is obviously not adjusting. I have ALWAYS been a tinkerer but I wonder what your thoughts are... can the guts of a vintage (50s) knob be repaired? Thank you for the "trade secrets" reveal.
Hello, I was given a Viking Stereophonic Model# RCS594 some 20 years ago, I believe this unit is about 60yrs old. It has sat in my basement and not been used at all. I do know it is full of dust and it did work really good when I got it. I recently powered it up and got nothing but static out of the speakers so I shut it back off. I do have some electrical knowledge but limited in tube amps. Whats the chances of this thing working after a serious clean up. I don't want to spend a lot on repairing, I do have all the tools mentioned except for signal generators and scope.
Hi, I'm sure that you could get her going again. It's just that the unit is 60 years old. I'm sure you have old capacitors as well as tubes that are shot. Maybe other issues at that age. You have to be careful in tube gear as the voltages are pretty high. Tube electronics can really hurt you if you are not careful.
@@vintageaudioaddict Hey, thanks for the reply. Like I said, it worked when I brought it home but it has sat and collected a lot of dust. Once I get it up on a bench my first thought was a thorough dust and clean, then a thorough inspection for anything obvious. If nothing is obvious I thought I would power it up again and look for any indications like smoke, smell, arcing, does this make sense?
I am new to this and nice video, but why did you not tell me what I can look into when xy happens? My 330c has more DC voltage on one channel than on the other, but you did not go into it on what I can look at.
Chris...awesome video. I have a Pioneer 1020L R2R that I am doing a electrolytic replacement and am now wishing I would have bumper up the voltage rating of the replacements. The schematics from HIFI engine are a definite must. Curious to what your thoughts are on the tantalum electrolytic capacitors? I have 5 of them that I could not find a direct replacement so I passed on replacing for now. Take care...
Your 1020L is a fine deck and thank you for the kind words! Get rid of those tantalum capacitors when you can. They have the same issues electrolytic capacitors have.
@@vintageaudioaddict Thanks Chris. What do you recommend I replace the tants with? They are 10uf @ 16V. Shoukd they be tants or can they be newer elys?
I envision a day when I can use a 3D printer with IoT to print out replacement parts for my tape deck. Many of those parts can probably be combined and use more advanced materials (ceramic composite). In the meantime, I have to tolerate curling of the edge of tapes with railroading and intermittent channel dropouts/fluctuating channel consistencies.
If the power transformer was bad on a beautiful Marrantz, I would find a suitable replacement transformer or even multiple transformers and put them in a case placed behind the unit to get it going. Too much to lose to make it a boat anchor.
So I was told I would not be able to get MOSFET's for a Luxman. I found same part numbers at New Jersey Semiconductor. Just wondering if anyone ordered parts there?
Does anyone know anything about the 1958 Magnavox model numberISP275F? no info on magnavox website, no images online, nothing. I did read the the Custom turntable is quite rare and that's the only thing I was able to locate.
UA-cam has needed a quality audio repair channel for quite some time. Thank you for going down this road.

Hey, Jack. Thanks for your kind words. Sorry about the email it really gets a little crazy sometimes. No way to read/respond to many of them. I'd never restore anything or get video's up on UA-cam. It's great that you got some test gear. Do some searches here on UA-cam for the information that you are looking for. A lot of good stuff here but sometimes it's hard to find exactly what you are looking for. Good Luck! It's a fun hobby.
if the gear is over 30yo, i replace all electrolytics. they are cheap and easy to replace. why risk it? i have been restoring vintage audio since late 70's and am too old to screw around. i also eliminate all ceramic caps as they are a huge source of noise. another component i always replace is composite resistors. i always use film resistors which are not a noise source. i also always use 1% resistors which allows for much easier balancing of the sides. i also like to shield signal wires as they also can introduce a lot of noise. if you do this yourself, the cost difference is not a big deal. it does take a lot more time, however. but when you are done, you will not believe your ears. when your gear is not fighting itself with unnecessary noise in the system, you end up with much more precise and detailed sound. your headroom will expand beyond what you thought possible and the music comes alive. i have taken very average vintage audio, rebuilt it and a/b tested against some of my customer's supper expensive new audiophile gear and blew them away every time. a well-tuned audio gear means you do not need 200W+ per channel to hear everything. you do not have to turn up the volume as much. it is tedious work and requires attention to detail, but it is not difficult.
Great overview, thanks. I am going to start repairing and upgrading a Bryston 2blp amplifier after new year's celebrations. This information will help.
Your welcome. Good luck with your repair!
Really appreciate your videos!!! Keep 'em coming please.
More to come! Thanks for watching!
enjoyed the video ! I am trying to get the balls to replacing the big electrolytic s in the power supply of my 1978 Nikko Alpha III power amp...the unit is in perfect, original operating shape now, so kind of a preemptive strike. Nothing in my electronics is newer than 1979 (except speakers) and it cranks. I really like the de-soldering gun you used, beats using braded or twisted wire I imagine !
Why weren't you teaching me while I was doing electronics engineering 30 years back 😭😭😀
very informative, thanks
You're welcome and thank you for watching.
Great yt suggestion!! new sub indeed! Thanks for sharing!
Awesome! Thank you! I appreciate it.
Very interesting overview! And it really makes me want to get some broken equipment and try to fix it. As soon as the flea markets and stores can open again (due to our tiny pandemic problem) I'm going to get all the stuff I need :D. Thanks for the inspiration and encouragement! All the best
Thanks! I'm glad that the video helped you out.
I always liked your style of explaining repairs. Just enough info that someone that knows what they are doing will be able to learn something new or get an idea of how to fix a unit they might have gave up on. In that spirit this video is great, but I don't think you should recommend, or even lightly imply, that someone that doesn't know how and doesn't know a tech should try and fix it themselves. Like you, I want this gear to survive and I wouldn't want people that don't have a clue to attempt a repair and further damage a unit to the point that it's no longer repairable by anyone! If they can't repair it and can't find someone to fix then maybe the best course of action is to sell it at a fair price given the condition. At least that way you are still giving that old unit a chance to bring someone joy again rather than end up in the trash heap.
Other than that, great video!
Thanks for sharing your comments. We all think differently and that's okay. Vintage audio repair is not terribly difficult IMO but it's because of the way I think. I think most folks that have learned a skill in life can learn other's. Thanks again!
@@vintageaudioaddict if only the most skilled were honest... they'd admit they've smoked a component or 2...
Merry christmas and awesome channel! Always worth the view!
Thanks! You too!
Thanks for sharing the helpful content and Happy Holidays!
Same to you! Thanks a lot for watching!
This video is awesome, thank you for sharing your knowledge.
Glad it was helpful!
How do you not love this guy. ❤️🫶🏼
What a great round up on starting to work on vintage gear!! Thx a lot for this inspiring video!
2 questions on the tool set: would you recommend to use a Dim Bulb Tester when powering up a piece of vintage gear for the first time (after examining the inside) in case there is an accidental short? And/or would you recommend to use a variac for powering up vintage gear slowly when stored for a longer time?
Thx a lot for sharing your experience and expertise!
You have some beautiful equipment.
Thanks
I like your foresight comments towards the end of the video.
Do you have any perspectives on regional climates and their effects on all this old stuff? Automobiles for example, rubber and plastics survive longer in the humid regions, steel and non ferrous metals however fair better in the arid southwest. How do these different climates effect electronics?
this is so incredible....great video
Thank you so much!
You and the 12voltvids guy should do a debate on whether to swap electrolytic caps or not. Live stream and give any donations to charity.
LOL....He's to smart for me.
Great clip. Very informative.
On question, how can I get the stereo to give a 16 ohms output at the same wattage? 🙂
I Really Appreciated The Video.......Thank You....
Glad it was helpful! Thank you for watching
My hobby is refurbishing console stereo's and to just swap out components is much easier
Thank you this is really helpful
Glad it was helpful! Thank you for watching.
Mouser or digikey, parts for my vintage disk cutter.......even cryystal cutter head, parts are all available....You can 3d print the knobs..with the correct specs..
I don't even care for electrolytic caps, I have literally bags of tantalum from Kemet, from 0.1 uF to 470 - Bought them for peanuts, around 95, from a local supplier that had to close down - Before you jump into the comments, I've never had a fire or explosion, those things are so little that you can replace them with one rated for double the voltage... They have even lower ESR, they can handle all audio frequencies whereas electros increase the impedance as the frequency goes higher. They're also much more stable, the value doesn't drift with temperature, leakage is zero and, most importantly, they last more than what I expect to live, so...
Just keep in mind that tantalum caps fail to a dead short.
You Look like a Line Backer!!!! You Was A Big Guy in Your Youth!!!!
In my younger years I did enjoy playing sports. Now it's eating and drinking to much, LOL. Thanks for watching.
great info. Thank you.
Glad it was helpful! Thank you for watching.
Awesome video!
Thanks!
Good stuff! Cheap and imprecisely manufactured small hex tools are the worst. They ruin a screw in no time. How well do the wrapped connections age in your experience?
Thanks! The wire wrapped connections seem to do fine. The issue is when you bend them to much. Then the wires will break but that's true for new wires also.
Hi Thank you for your channel. Great videos. What about tuners... video. AM FM. What involves, tools. that would be great. I have 4 old receivers, two of them the radio performs really bad. Regards from Argentina
Greeting from the USA and thank you for your kind words. Yes, that is a good idea. I will try to put something together in the future.
Damn Sir That is The Best Marantz I Ever Seen in My Life!!!!!!!! Whats the Model number!!!
I believe I show a Marantz 2500 and a 2270 in the video. Thanks for watching.
My wife and I have been collecting mid/mod furniture, lamps, etc for about 10 years. We are looking at a Delmonico piece and I was/am reluctant to buy. It lights up, when "radio" button is pushed, there is sound (static only) but the tuner knob/guts is obviously not adjusting. I have ALWAYS been a tinkerer but I wonder what your thoughts are... can the guts of a vintage (50s) knob be repaired? Thank you for the "trade secrets" reveal.
Great video!!
Thanks!
Great video! Can you tell me what signal generator you’re using? Thanks, Dave in Central, NY.
Thanks! It's a Siglent SDG1000.
here in Australia is RS component and element14 they will ship to the usa
At minute 25 you talked about those diodes. in my sansui G-6000 I have red and black ones. should I replace them ? if so, with what?
Hello, I was given a Viking Stereophonic Model# RCS594 some 20 years ago, I believe this unit is about 60yrs old. It has sat in my basement and not been used at all. I do know it is full of dust and it did work really good when I got it. I recently powered it up and got nothing but static out of the speakers so I shut it back off. I do have some electrical knowledge but limited in tube amps. Whats the chances of this thing working after a serious clean up. I don't want to spend a lot on repairing, I do have all the tools mentioned except for signal generators and scope.
Hi, I'm sure that you could get her going again. It's just that the unit is 60 years old. I'm sure you have old capacitors as well as tubes that are shot. Maybe other issues at that age. You have to be careful in tube gear as the voltages are pretty high. Tube electronics can really hurt you if you are not careful.
@@vintageaudioaddict Hey, thanks for the reply. Like I said, it worked when I brought it home but it has sat and collected a lot of dust. Once I get it up on a bench my first thought was a thorough dust and clean, then a thorough inspection for anything obvious. If nothing is obvious I thought I would power it up again and look for any indications like smoke, smell, arcing, does this make sense?
I bet you cannot find an attenuator knob for one of the Luxman M02 channels
I am new to this and nice video, but why did you not tell me what I can look into when xy happens? My 330c has more DC voltage on one channel than on the other, but you did not go into it on what I can look at.
Thanks. It's difficult to provide advice for every possible failure. This video is just a first step to troubleshooting. Thanks again.
Chris...awesome video. I have a Pioneer 1020L R2R that I am doing a electrolytic replacement and am now wishing I would have bumper up the voltage rating of the replacements. The schematics from HIFI engine are a definite must. Curious to what your thoughts are on the tantalum electrolytic capacitors? I have 5 of them that I could not find a direct replacement so I passed on replacing for now. Take care...
Your 1020L is a fine deck and thank you for the kind words! Get rid of those tantalum capacitors when you can. They have the same issues electrolytic capacitors have.
@@vintageaudioaddict Thanks Chris. What do you recommend I replace the tants with? They are 10uf @ 16V. Shoukd they be tants or can they be newer elys?
I envision a day when I can use a 3D printer with IoT to print out replacement parts for my tape deck. Many of those parts can probably be combined and use more advanced materials (ceramic composite). In the meantime, I have to tolerate curling of the edge of tapes with railroading and intermittent channel dropouts/fluctuating channel consistencies.
If the power transformer was bad on a beautiful Marrantz, I would find a suitable replacement transformer or even multiple transformers and put them in a case placed behind the unit to get it going. Too much to lose to make it a boat anchor.
LOL, thanks for watching!
I have a optonica sm 1515 b amplifier and Sony tck2a cassette deck if a power transformer goes can they be fixed both 1978 models
Possibly but power transformers are one of those parts that are difficult to find.
Good advise on not buying from eBay.
I have a finished Chinese integrated amp using Sanken transistors. Interested in repairing?
So I was told I would not be able to get MOSFET's for a Luxman. I found same part numbers at New Jersey Semiconductor. Just wondering if anyone ordered parts there?
Does anyone know anything about the 1958 Magnavox model numberISP275F? no info on magnavox website, no images online, nothing. I did read the the Custom turntable is quite rare and that's the only thing I was able to locate.
Will you work on Trc 500 walkie talkies
Thanks for asking but I don't have any experience with walkie talkies.
Esse Marantz está a venda ?
