Received a badly repaired 4 channel amp. Its analog with Tip transistors..
Removed for testing all outpust. Had a short in the ps for op amps. All op amps was changed before, inductor and transformer was liftet before. So i expect over voltage at the op´s.
Problem is now, i cant read anymore the value of a transistor. Mostyl they installed CEN 2N6715 and 25 type. But iam not sure. Maybe somebody have similar diagram.

Whenever asking for anything from a manufacturer, the first email should simply be asking if the email is a good email and nothing more. If you get a reply to that, you have a better idea whether they're ignoring you or simply didn't get an email asking for help.
