You can always create a Youtube Account and, start making reviews about the amplifiers you own. The Home Audio market has done it for years. However, the Professional Audio Market tends to be non-existent on such reviews regarding amplifiers.

You may gain more traffic on your channel if you bench the amplifiers. There are a few channels that offer such videos and they have a reasonable amount of traffic. You will not get the general consumer that buys based on marketing hype. Your traffic will be viewers that are more on the technical side of things. Similar to EEVBlog.

i would like there to be more documentation of repairs of power amps on youtube channels. i think it would be a valuable contribution to the internet, to just talk through how someone goes about identifying and addressing different problems with amplifiers.

Carver PM 1200 the worst amp design i ever worked so far... i almost want to throw it away but i changed my mind and give it a chance to life again...so the list of faults were:
-faulty low rails capacitors blown up -faulty bridge rectifiers from diodes went to resistors -faulty both fans wont spin even by force -faulty both pots didn't move at all,like welded -thermal paste dry out..more like a concrete... -rusted bolts and nuts shorting couple transistors to case -a lot of oxide on the circuits hard to clean and hard to solder on After sorting all these out and made a small modd to the low voltage caps i test it and works flawless,now i need to order 4 small profile 2200-4700uf/80-100v caps and fix them as my one are way bigger and i cannot fix the input board back...

To be honest i've no ideea,looks like but is not...as not all the parts were rusty...i think has something to do with club smokes and carbonic ice,as the most affected areas were where the fans circulates air...so it cannot be water damage...unless was playing on a pool....i don't know what to say.

Doing a lot of Electrical work in areas surrounded by sea water, such corrosion is very commonly found on a lot of metal objects conducting electricity (Inside Panel Boxes). Usually very damp environments (Basements) with a lot of salt in the air.

"Carver PM 1200 the worst amp design i ever worked so far..." Aaah - the famous "Magnetic Field Amplifier" design. I'm surprised that there are any of those still about. They were terrible. The exact opposite of KISS....  |
