I am only getting 0.152v ac on the output when engaged. I believe the transformer is oriented correctly and solder joints appear clean. I am getting 0.14v ac @ U2 pin 4 and U2 has power. I hear the relay click when taking out of bypass. I also tried cleaning the tube pins. Please advise, Thank you
+15.6 v
-15.56v
B+ 45v

Remove U4.
What values (DC and AC) do you get on TP1 to TP4 in the initial conditions here.

[Ben]

 0.05vac and 29.69vdc @ TP1
0.077vac and .258vdc @ TP4

[Ben]

I reheated all solder joints and rechecked for bridging or shorts, no change
Thanks,
Ben

Can you please also report the values on TP2 and TP3?

[Ben]

TP2= 0.297 VAC and 0.057 VDC
TP3= 0.077 VAC and 0 VDC

Pot 1, R1 and R2 test ok as well
Thanks,
