15vdc on both sides. At this point I'm convinced that the problem is at V12. What I don't understand is why I have the correct negative voltage on one side of the RF choke but the incorrect positive voltage at the pin. I tried removing the neutralizing gimmick (unfortunately I destroyed it in the process) with no change. I also tried bypassing the RF choke and you lose the negative voltage all together. My gut tells me it's something with A20 since that's the only other thing tied into pin 2 of V12. Pin 7 and pin 2 are tied into one another through A20 and pin 7 has the correct voltage but pin 2 does not. My limited understanding of how tubes function in circuit doesn't help though so it could be something else at V12.
