Chroma w/out Luminance in CTC-11?

[freakaftr8]

Curious to what causes tuner drift like that between channels.

I thought tuners were on a keyed shaft and wont allow the contacts to drift off. If someone twisted the tuner knob hard I suppose it could bend the shaft causing an alignment problem between the key and the contacts. Mabye an adjustment of some type.

Thanks for all of the tips. I like these easy fixes, even when I don't think of them first.

This one looks promising. Nice bright CRT, and the convergence is already better than on my "restored" CTC-11, which I slaved for hours to improve.

Now I am on to other issues, like replacing electrolytics and trying to fix the blasted tuner, which only receives stations when I turn it between channels. DeOxit didn't improve it, and I'm loath to try scrubbing the contacts for fear of making it worse. My other 11 has the same tuner problem.
