Bias is way too high. With pots turned all the way down, bias is leveling off at .70. I thoroughly cleaned and tightened all the sockets. And still have the problem.
Here are some pertinent values:
red/blk wire bias connection 55vac
Other end of diode -45vdc
each location of pin 6 at board -22.3 to -23
Across pin 2 and 7 of each output tube 7vac
rec tube across pin 2 and 8 5.5 vac
rec tube pin 4 and 6 379vac
So have I got a bad diode (or did I toast it soldering it in place)? Or should I look somewhere else? Can I replace that diode with a 1N4007 or do I need to go the electronics store?
Thanks in advance for any and all help.
