I was employed as a commercial audio technician for several years. There are many repair/restoration methods that I would love to help this guy with. Nevertheless, I give my admiration for his effort and willingness to expose himself to the scrutiny of the world of repair technicians. The honest truth: we can ALL learn something from every technician out there! 😊 Keep the comments coming. 👍

I'm glad I no longer need to do commercial repair work. I like to take my time and make everything pretty instead of hustling to get the maximum amount of work turned out in a day. Now I just build or repair for myself. So I take my time, thoroughly clean everything, bend all the leads perfectly, and solder everything so it's not just functional, but pretty. Everything looks and sounds the same on the outside, but everything looks really nice, better than new on the inside, and I know it. The electrons don't care, but I do.

Dzień dobry! Też lubię naprawiać stare audio i poprawiać wygląd wnętrza. Układać równo przewody i poprawiać fabryczne lutowanie. Koledzy mówią że sprzęt ma działać a nie wyglądać, ale to taka moja terapia. Z Bogiem!

Thats not a genuine Crest Audio amplifier.... Genuine Crest Audio amplifiers are made in the USA, and they dont make a CA20 model.... Can clearly see by the internals, that its a chinese fake copy amp... (ive worked on MANY genuine Crest Audio amps over the years, So know the internals very well)

Is it a kapton tape between transistors and coolers? Washers should have very low thermal resistance, so kapton tape shouldn't be used here. Those old white/transparent washers were better than kapton. Even mica washers will be better.

As a person whom restores vintge hi fi for a hobby, ive never in my life seen anyone test equipment so randomly. I strongly reccomend anyone watching this video or others like it NOT to tey this sort of repair. It is dangerous and those big capacitors if not disscharged can give you a nasty shock and then theres dealing with high voltage. And all those caps would have been worth replacing.
