Starting a Restoration on a 1951 RCA 7T111B

[Aperna1985]

I might have a CFL bulb I have to look.

The 6GB6G rectifier tube tests good on my tube tester and shows no leakage. It's not super strong just in the middle and does have a little bit of a blue glow. The TV is off in the picture.

I don't know how to check frequency, is there a way without a scope?

I have those tube adapters that have tabs to check voltage so I will try to run through the horizontal circuit this weekend.
