We took it to the local tv shop for repair ONCE when the sound became distorted and a trip to the drug store tube tester didn't cure the problem. I think they put a resistor in the set.
Just a few years ago I finally replaced the original crt and two paper capacitors to cure some small vertical shrinkage horizontal issues. So, nearly 60 years of service with hardly any repair or restoration. That's one good set!

Was that the Microgrid 390 model?
They originally came through with a 6BZ8/X155 as an RF amp. IIRC, that was Philco's own tube. Most techs replaced them with a 6BQ7 or 6BZ7.
It also had a 90 degree CRT. Great working set.
