The CTC-16X is also available.

The ETF Museum database is the "go-to" place for vintage B&W & color TV data.

Hope this helps,

Thanks for the info, but I've been using this SAMS from their site, I was looking for the RCA service manual. The RCA manual has a little bit more information about adjusting the set, I was able to buy one online.

Onto purity and convergence. Does anyone reccomend a good lubricant for the convergence pots? I've got a couple that are stiff, and was able to get a few moving with some contact cleaner, but they're still harder to turn than some of the other pots on the board. I was thinking dielectric grease, or I've seen F5 fader lube/cleaner reccomended for other applications.

This is par for the course with the pots on the convergence PCB,they always tend to be hard to turn no matter what, as they are 2W wire type pots, and I have never seen one that was not stiff, and It's good that they are, cause you dont want them to move once set.
I would leave them as is.

If convergence are ok, and not have bad contacts, is possible to leave as-is.
But once I had bad contact issues with the a convergence board that makes the vertical jumps or jitter. Cleaning the pots solved the problem.
