Hello there...
I need this....well...for yesterday.
The unit came with service LED flashing with about 0.3Hz.
The main fuse Ok, Voltages Ok, no sound/hum/noise on speakers. The active amp has three identical modules done with through hole components. The first module has some kind of control card attached together and, I guess, that control card is aggregation point for mute/alarm/temp/signal lines to backpanel, together with leds. I have tried to find eventually failed power module by interchanging them and stack together with control board but everything I got is the same - error blinking.
I am trying to find service manual for this poweramp but without success.
