New to Forum- 47-1230 is my 1st Restoration
#37

So I did some resistance checks on the affected tube pins and circuits and found an open 68 ohm resistor on 6BA6 pin 7. I changed that resistor and corrected that. On 7F8 I found pins 3 & 6 open resistance. Tonight I highlighted my schematic for those circuits and the components I need to check tomorrow. I also found I have 6AB6 Pin 6 wired to C102A and I believe it should be C102B. C102A has the R100 resistor in that circuit whereas C102B does not, and according to the schematic Pin 6 does not connect to the R100 resistor. I plan to change that tomorrow as well, and I'm hoping that since the relationship of my off voltages and resistances seem to affect the 7F8, 6BA6, & 7R7 circuits and they have several components in common, when I find the culprit or culprits, all of my voltages and resistances will come into line.
