Hi everyone. My amp is dead, no std by, no relay click. All fuses is perfect, primary on main transf. is excellent.
On the AC Board, after diode on pin 2 (12V) i have 16v, pin 3 (P_OFF) i have 12 v, and pin 4 (P.RY)i have 0V. All diodes, fuses and resistors on AC Board are fine.
On IC1206 (NJM2103) pin 5 i have 16v, but on 8 pin i have 0V.
On Q1205 i don't have 6.8v/6.2v only 16v on the collector.
My question is... in this amp, which parts /elements/ responsible for stand by voltages. I have 0.7v on stand by, but i can't see on service manual, where is a stand by supply (5v)?
