Can you tell me the Class of this amplifier?
I don't know if is Class AB or Class B.
Thank you.

I recently bought one of these old YAMAHA RX 797 receivers from Ebay. It has the same sort of issue the one you fixed had. When turning on the unit it powers on but after a few seconds powers off. I'm not an electronics repair person but I would like to have it fixed asap. You mentioned about the UK model having a different rating or type of capacitor compared to the US model. I have a friend that does some electronics repairs and he said if I order the correct capacitor he could install it for me. Where do you buy/source capacitors online? I will run the diagnostics test and see what it shows but I'm feeling it's the capacitor.

As a complete amateur I managed to repair my amp by following your instructions. Was a very straightforward fix.

Brilliant!

You are right Waleed. I think research is probably one of the most important parts of our repair. I always start with research first.

Thanks Albert.
You can spend a lot of wasted time searching for difficult faults, but it's a good feeling if you are able to repair it.
