Anyone willing to offer a little troubleshooting help? I am working on a Sansui AU 317. Dead left channel. I have isolated the problem with to a stage just after the input fet IC on the power amp board. TR01 collector has a nasty corrupted signal instead of a nice sine wave. I checked the input fet and all of the adjacent transistors with a transistor analyzer. They are all good. Do1 also checks ok.
