Shot in the dark question X88R

[joesatch]

Does anyone have the plate voltages (V1,V2,V3 etc) on this unit? Not the B+ but the voltages at the plate on the preamp tubes? My B+ is around 360vdc before plate resistors on the various stages. This is a critical piece of information that is missing from the various schematics on the interwebs.

I don't have your answer but 360V is dead on in the SLO. I don't imagine Soldano deviated very far from his favorite specs.
