Thanks Bob, so am I.
So I tried installing the HV pot, but it didn't make any difference. Even with the regulator not drawing any current at all with the set at minimum brightness, it still didn't go over 18kv. Also bumped up the horizontal drive by changing the value of a resistor on the horizontal board, but no dice- still only 18kv. I know the CTC-5 chassis is known to be a little on the weak side, but are they so weak they aren't able to put out the 20kv called for in the manual? Nothing I try seems to work, but at least horizontal output tube cathode current is staying under 200ma. If it turns out the HV really is weak and that's just the way it is, I guess I'll just have to live with it. But I'd prefer if I could get the full 20kv, I think it would bring a little more brightness to the table.
I suppose I could try one of those more efficient stick HV rectifiers, but I doubt I'd get 20kv even with that. Need ideas.
