The other pins are within 2 volts of the diagram . I have checked the volt dropping resistor and it is good, b plus is 8 volts 8 high, there are 3 coils between b plus drop resistor and pin 5 and they show correct resistance.
I am thinking it is a signal issue.
Since the B plus is good and the tubes output voltage is low then it is a bias/signal issue.
Am I right?
