Hello,
was wondering if anyone could help. Trying to fix this amp for a friend and its producing humming / buzzing sound regardless of volume. It has jumper cables at back and I know for a fact the preamp is working fine so its the power amp not working. I have also tried replacing a few caps in the protection circuitary that may casue this but still getting a loud buzzing sound from it. I also tried measuring dc offset and there was none. I'm stuck! Any suggestions please?
