I've got a 2245 opened up and it needs some work. The first thing I want to get figured is a bad channel.
I have signal generator and oscope but I'm not very familiar with the schematic so I thought I would reach out for some help tracking down the issue.
I've deoxited the pots and switches. No luck.
I took the preout to another amp and the distortion is still there. So I guess that means it's before the amp board. Correct me if I'm wrong.
Low channel and distortion is on the right side, left is clear and strong.
Distortion is present using headphone jack as well as speakers.
I have the schematic and service manual.
I'm hoping someone can help me check voltage in some key places to track down the issue.
Thanks in advance,
Gary
