reviewing the schematics I can see the ctc-5 has the 82k and the ctc-5N has the 100k for R603. I have a ctc-5N and it has the 82k, hmmmm.

the ctc-7 has a different setup, with a pot for drive adj, and a cap in series with the 100k/pot.

Question for Pentode, did you check the cathode current before and after the switch from 82k to 100k?

I had no evidence of a drive bar on my set so I may try changing the resistor if for no other reason to see if I can get that cathode current down. I still have to try it with with the new convergence pots so I can get a good reading in the cathode voltage of the horz out tube. It was high before, but I think that was just due to the increased resistance of the old pots. IIRC the called for cathode voltage is 7.5 v and I was at 12v. So will base line it with the new pots, get a revised cathode voltage, then experiment with the R603.

I did check the current (200ma) but the RCA schematic did not specify what it should be, just gave the cathode voltage. I suspect 200ma was about right but would like it to be a low as possible. I did adj the eff coil for the dip.
