yes, all new tubes installed
i have with a 500ohm resistor kit i put togetherchassis mounted i am at 283v.

suggestions?

put dual 300 in series? the mouser ones or another solution?

i have to wonder if there isnt still a problem,,, although ive enjoyed using the radio this eve on my work bench.
i let it run for about 4 hrs straight and the 500 ohm resistor is holding steady stong, no changes to the voltage drop across it. Also my candohm is still holding down 22v.
