Hiya troops, Having a wee problem with the above amp. After a years inactivity this amp when plugged in goes into "standby" ( E version ) but will not power up.
So far I have checked the obvious, fuses etc, then noticed that the power relay (RY 90) is not operating, so checked out (Q952) relay driver, thats Ok, and temporarily applying +5 to that transistor base activated the relay, but still no power-up. I'm starting to wonder about the main controller (ic 202) argh!
Any suggestions, common faults
Skyhook.
