Today's Mystery Guest (RCA CTC-4)

Thanks, that gives me some things to try. I haven't redone the alignment procedure since the latest replacements (which included a couple of resistors on the demodulators).

The tint (hue) control does have an effect. Colors shift around in the bars, but they are never correct.

Edit: I still haven't done the alignment, but here are quick photos showing the results of shorting the demodulators.

1. Demodulators normal (nothing shorted). Wrong colors, of course:



2. Demodulator pin 1 shorted:



3. Demodulator pin 6 shorted:



The tint control affects colors in both cases.

Gotta run some errands, but I can return to it this evening.
