I need to dig into my CTC-11 tuner as well. It loses audio; tweaking the knob just right will restore it. One night while watching it I had a revelation-I thought of just what the problem might be. Trouble is, I forgot it! I would have worked on it right then but of course it is big and heavy, as is the 21" bw Emerson sitting on top of it...

My American TV was the same way, only the spring action in the tuner is very strong so it was almost impossible to situate between channels. All it took to make it right was some tuner cleaner and paper towel to wipe the grime off the contacts.

I will try to get something down there for manual cleaning. Maybe a long forceps or tweezers holding a tiny fold of lint-free cloth. I can also inspect to see if one wafer has been nudged out and un-keyed from position.
If this cure works on my dollar TV, I'll repeat it on my "good" CTC-11. Maybe I can ID which tuner I have, too. Sams shows various flavors of this chassis: A, B, etc. I don't know if the A-B-C-etc. signifies electronic differences on the main chassis or just different options for tuner & remote. This set is plain Jane: no UHF, no remote. The model number on the back is 212F752MV, not listed on the front page of Sams, although when I looked it up on samswebsite.com, I was referred to the same Sams, set 550 folder 2. I guess some of that model number refers to cabinet style, color, & whatnot. Phil Nelson
