Thanks for the suggestions. That voltage is a tad low at 306v but should be ok, I think. As a matter of course I replace all caps and out of tolerance resistors, although I didn’t do the ones in the tone control…didn’t seem to be crucial and the control seems to be working fine. I have a couple of other 6A7’s and 39/44’s that I can try switching out. I don’t know the status of the latter that I have as my tester (Precision 640 emission tester) doesn’t have setting data for that tube. Hopefully, swapping out the tubes will help. Otherwise, as previously mentioned, the radio sounds good but it’s just annoying that the meter doesn’t function.
