Hello friend, first of all, thank you very much for your interest. Are you sure about the D801 24 VOLT zener diode? Can it be a fast diode? Both channels of the amplifier are solid. I listen to good quality music. As I said, the role sometimes turns on and off every minute, sometimes it works for 5 minutes without any problems. FM mode does not work, only SW MODE works. AM FM does not have any sound. No, I want to fix this part first, I'm about to go crazy, should I change the materials you mentioned?
