I have a Dynakit Stereo 70 Amp and Pre. I was listening to a record and the sound stopped. I was out of the room when it happened so not didn't see anything or hear anything funny, just came in and the record was going and there was no sound. Power is working on both. Tubes appear to be working on both. I tried an alternate (line-in) input and that's not working either.
I've gotten ok at tube replacement and bias work and i'm pretty good as a troubleshooter in general but my experience with analogue audio repair is pretty much non-existant in terms of replacing other parts.
Do you have any suggestions in terms of how to narrow down the problem further or steps I may have overlooked?
Thanks so much for you help. This system is crucial to my life!
