Just wanted to share this schema..... I have to of this amps, bought them new for about 15 years ago, and now they produse a low sound in mid and high when idling... caps changing perhaps? any toughts?
they also been to the seller for a upgrade abouth 7-8 years ago... where there was added some transistors and what not... dont know if that really helpt. will post pics on that later. anyone ever owned these amps.. thought on quality?? they served me well, so no regrets, but want to adress the zzzzzzumming when idling. zumming on both amps= same problem? also want to know what the different trimpots r... ie bias, dc and so on
thanks for any input
Regards
