Power Amp (AWH-019) not functioning.
By jacolucci, 15. October 2021, 18:10.
Replaced all caps and transistors. Having difficulty tracing circuit due to mirror layout of schematic. Getting proper voltages however finals (emmiters) showing no voltage. Really stumped on this one. Audio getting to board is good, however nothing past first transistors.
