Buzzing output pair after 20 seconds of playback
Hi all, I have 5 speakers hooked up to this amplifier. I have problems with surround LR pair.
ANSWERS:
yfyfyf sounds like something getting hot and fails. Since it is both surround channels it would eliminate the amp IC's for those channels. Since you do have the service manual, I suggest that you take it apart and take a closer look D amp assembly. Check the FET's and see if they show any signs of overheating. Post images with your question so we can see what you see. Use this guide for that.
