CTC 10 HV affected by brightness

If you had a shorted turn it wouldn’t work at all.

Current goes up because you have a heavy load on it, which is normal. What does “messing around all night” mean? Did you run the setup procedure? Did you verify 1ua cathode current on the shunt tube with a dark screen? Did you null the efficiency coil? Did you verify the double humped waveform with a scope?

You haven’t given us much to help solve your issue...

I don’t wanna sound like an asshole but I don’t really know what half the stuff is you’re talking about. I don’t have a ton of color set experience

Do you have the Sam's or RCA service data for your set? (The Sam's is available for free on the ETFs website if you navigate to early color TV then technical information) The procedures Nick/miniman mentions are standard service adjustment procedures detailed in both of those manuals and are the first things you should do when you experience incorrect horizontal performance.

Nulling the efficiency coil especially should be done to all RCAs that have been brought out of decade long dormancies ...and might be all it needs if you haven't done that yet.
