Arran,
My power tube is a 50A5. I replaced the 470k resistor on the plate. The 14B6 is the 2nd detector. It also has a 470k resistor on the plate which I also replaced. I get no hum touching a screwdriver to the center term on the volume control. I do get static when I tap the 50A5. I'll be testing the tubes tomorrow and I'll give a report.
Thanks,
Eric
