Rca ctc-5

I don't know if mine has the mods done to it or not, and I'm 950 miles away from being able to find out any time soon. But as I said, yours must be the exception rather than the rule. Every single one I've run into so far has been really weak, even with pots for HV and drive mine fails miserably to sustain 22kv at anything close to a normal viewing brightness level. Count your lucky stars.

I am currently hundreds of miles away as well from working on my set. But I have exactly the same problems with my CTC5 as Nick. The shunt regulator is hardly passing any current because my set is only generating about 22kV with the shunt removed.

I am curious if in the murky past someone hasn't replaced the Horizontal Output Transformer in your set. Are there any traces of resoldering?
