Hello,
I have a Korea version of SAE A202 power amplifier and it had worked well till a week ago.
10 years ago I replaced two output relays of the A202 and added some film capacitors to the power line and also replaced input capacitors with film capacitors
I was satisfied with the result..
A weak ago I realigned my stereo systems to locate new input source equipment 'network player' to my audio system.
After realignment I put all power plugs to the AC power line on the wall no stand-by LED of A202 turned on and any switches did not work.
I opened the cover and check fuses and power transformer with my multi-meter and I did not find any problem on main power line and fuses..
I did not check control part of power line which seemed be constructed with separated transformers and B+.
I assume this control part of power line may cause my current problem.
Any comments or recommendations would be appreciated.
