SAE P102 preamplifier problem. Schematic needed please help!
Hi, can you help me out here? My preamp lost the volume leds and the standby led. Although they test good, it must be a driver or relay. They were intermittent for a while now fully dead. Thats to say that once in a while the standby led would come back on, and if I turned it on the volume leds were back but then it would vanish again. Im sure its some common voltage or ground link thats doing it or a sticky relay. Please help.
