Restoring an RCA CTC-10 "Wynnwood".

That's the thing, the screens do what they should but the green and blue drive controls seem to do nothing, or perhaps it's just too dim to see.

The rejuved tube checks like new on my B&K 466 but it could be wrong, I'll check it again with the Beltron or the Sencore tonight and see what they say.

It might just be easiest to put the new CRT in and see what happens, I need to make sure the shadow mask is ok anyhow since it was shipped to me years ago, I don't see any debris inside so I'm pretty sure it's ok.

if the voltages are off and the video out tube is good I would look around the service switch and the various power resistors there. Also the coils involved.

try adj the brightness while measuring the red cathode of the CRT, should be 360 and 280 from fully CCW to fully CW
