Good..Can you post a photo of your main filter caps? Both topside and bottom side?Yeah, I checked their datasheet and aligned the transistors with the diagram printed on the PCB before soldering.

Are you seeing -41vdc on pin 10 of the AWR-060 power supply board?
Looks OK. And your getting +/- 30volts DC at the collectors of the outputs.Of course. 6800uF 50v Nichivons. I thought I wired them in correctly.
Super..I'm seeing -47v there.

Close enough.+33 at Q11/12, -33 at Q13/14.
Are the two STV3 diodes still intact ( no broken leads)?
For some reason those STV diodes are prone to breakage of the leads. Thats why I asked.They all look good to me.

Have you tested Q5-Q10 out of circuit?
? Usually there black or tan in color. Horseshoe shaped. And fastened to the large to the heatsink.The red and white ones on the power amp board,

D5 and D6 Soldered to the amplifier board and screw mounted to the heatsink.
Happy hunting. I have no more suggestions until we know the condition of all the transistors on the amplifier board.I have not yet, I'll pull and test them when I have a chance.
