I got an SA-15 amplifier, which I want to restore:
The previous owner unsoldered many parts from it for his own needs, such as potentiometers, capacitors and the audio amplifier chip itself.
I managed to determine the approximate amplifier chip by the pinout on the board, it is AN7161N, and accordingly those capacitors that should be installed with it.
Now I need to determine the remaining capacitors on the board, but unfortunately I could not find any similar diagram on the Internet.
I only found a photo of a disassembled SA-25:
The PCB is exactly the same, but it does not show what potentiometers and capacitors are there.
Maybe someone has the same SA-15/SA-25 amplifiers or their diagram?
