Hi
When testing voltages after installing the board
with the rectifier only in I get 396ish on all plates
checking at the 32/32 and then at different points in the circuit i get 396
It almost seems like the power resistors are shorted and dont reduce plate current to each Mini circuit/preamp etc
I know the directions say voltages will be higher without
tubes. But it doesnt seem right to have the entire b plus everywhere?
i will triple plus check wiring again
But I was hoping someone might be able to steer me in the tight direction.
Im not sure if a shorted input Jack from over heating the sleeve could cause this issue
Its probably a wrong wiring somewhere
but so far i cant find it
thanks for any help
FYI I can trace the jumper wire with a continuity/ resistance on the back of the board and it seems to be correct

Hi All
never mind I figured it out
I just misinterpreted the testing voltages section
It does mention you will have higher voltages than written on the schematic. But it didn't mention they could be as high as the 1st B plus. Either way I tried a similar amp and saw similar voltages so I felt safe moving on to adding tge tubes while monitoring the plates
All seems ok now
Thanks
hope everyone is doing well
