After reading my post I just realized I prob need to take it off standby lol for correct measurements - correct?I was able to get a reading on the impedance selector and output jacks.
From B+ CT to all impedence taps I’m getting 3.80 k ohms. This also the measurement on the jacks.
I measured voltage with tubes out amp warmed on standby I’m getting the following:
Pin 5 all tubes = -45 vdc
Pin 3 v4 = 0
Pin 3 v5 = -285 vdc
Pin 3 V6 = -285 vdc
Pin 3 v7 = 0
Funky - what is this telling me?
I also tried jumping the effects loop no change.
It’s pretty evident I’ve got a plate voltage issue - mind you this is still with the potential bad socket at V6 and a burnt bias feed resistor on V6
