Clean channel is shot how exactly? What do you mean by "shot" ? Did someone shoot your amp? That can stop them working.

Which test point? With 68 milliVolts of bias the power amp won't work at all.

R57, R58, V3 etc don't mean anything to anyone without a link to the schematic.

Hi Guys - So I've got a 1996 Hot Rod Deville.

1) Clean Channel is shot after I turn it past 2-3.
2) 68MV at the bias point
2) Checked all the suspect resistors (R57+R58) (R53+R54) (Ceramic R78+R79) (R61=R62)and every other flippin component on the lower smaller tube board every thing reads within spec.
3) Tubes have been swapped (v1 through v6)
4) Deoxit all tube sockets
5) Reflowed all the solder joints (Including the tube pins of all sockets)
6) Reading 499V on the Power Tube Sockets Pin 3
7) On tube v3 187V on pin 1 and ZERO on pin 6???

Anyone ever had weird ones like this? Any other thing I'm missing
