Ok so I have stayed up way too late too many nights lately with this piece of gear and upon Bob's advice I have decided to start over with a single thread. I am going to ask about a single issue first before I even discuss any of the other issues as this single issue may be the causative factor for the others. Okay so the power suppl;y voltages are as follows:
S- 456v
T- 406v
U- 376v
V- 225v
W- 256v
Y- 295v
Z- 179v
I first thought that I had high ripple on the supplies but i have since verified that all of these supplies are clean and not full of ripple. I had a grounding issue with the scope probe. Supply Y is the first DC supply after the first two 10K ohm dropping resistors and by the math for a voltage divider circuit this voltage looks correct for the voltage divider circuit with no load. However, we know that is not correct as the two 12AX7 tubes in the phono circuit should be conducting and dropping this voltage but we also know that this is not happening. The big question is why not? Looking at the schematic for VI and V2 I have verified that each resistor is good. There just isn't that much in this circuit. Please tell me what I am missing here. Is it a grounding issue?
