Thank you for the suggestion. I did some more testing and found I don't have filament voltage. It looks like part of the candohm resistor has gone bad. I'm not getting any voltage on the last post after the R100C resistor and nothing on the filament pin on 3Q5. I just placed an order for a 900 Ohm 5W replacement. I'll keep everyone posted once I solder in the replacement resistor. Fingers crossed I can at least get the tubes warming.
