Another cool acquisition to that impressive early color collection of yours, Nick! And a refreshing change from all those RCAs (a few more of 'em and old Sarnoff is probably gonna start payin' ya visits to see his products LOL.).

Pulled the chassis, it's one heck of a dirtball. Dirt mixed with nicotine, actually.
The CRT and mounting hardware didn't fare any better, basically anything with voltage moving through it attracted this crap. The crud eventually soaked up moisture, so anything made of steel has a nice patina on it now. Probably the worst smokers set I've seen yet. Oddly, the yoke cover was almost completely intact. Usually these things are disintegrated, but only the edges on this one were deteriorated. All the same, I decided to replace it with one of the ones Bob made. They fit really nice, just drill 4 holes and mount the old shield to it with non magnetic hardware.

From what I can tell, this set is an odd combination of CTC-4 and 21-CT-55 circuits. So I still consider it an RCA- in Sylvania clothing.

God, I hate smokers sets....
^ That was one wipe with bathroom cleaner. I had already gone over the whole cabinet at this point, and filled an entire trash bag with what used to be white paper towels. Then it dawned on me to just stick the rest of the parts in the tub, and let the cleaner soak in a while.

Don't pass up the dishwasher option to do some cleaning.
That's a helluva nice set. |

Are thos red rods like remote control for rim magnets? Never seen that before.

Yep, edge purity magnet 'control rods'. The cabinet is so cramped that it would be impossible to adjust them without those rods, and even with them it's not a perfect solution. It would have been a better idea to do what RCA did with the CTC-5, which has access to the magnets through the front bezel. I think on the 5 you remove the bezel and glass, then tweak the magnets with a screwdriver.

What's bad for the owner is good for the set.
Just think of that gunk as Cosmoline, it does a pretty good job of preventing rust and corrosion (on metal, not so much in lungs). |

What Eric says.
I've seen some absolutely BLACK smoker sets that are totally rust free under all that crap. Just wait until you fire it up. Your friends will think you are chain smoking, again!! |

Wish that were so- fact is the nicotine is sticky, so it attracts dust. All it takes is the dust to soak up some moisture, and everything gets rusty in a hurry. I was able to get most of the rust off with sandpaper, but the pitting remains. I just hope the electronics are still good...

Holy re-cap-a-thon, Batman....
And that's only about 90% done with the paper ones, I haven't even started on the power supply lytics. For that, I need the Sams to arrive so I don't f*ck something up. There seems to be a quad a 200uf@300v caps right in the middle of the main chassis, and a slew of others strewn about the chassis. I count 16 or so, not counting the random 4uf ones for the video circuits that I already replaced. You can tell that Sylvania had to change a few things to avoid RCA running them down for patent infringement. For example the demod driver tube in the CTC-4 is a 6AG7 type, and here there's a 6CL6. In the audio section where the CTC-4 uses a 6AQ5 output, this set has a 6W6GT. It'll be interesting to do a head to head with my Director 21, to see which is the better performer.

Is it an I-Q wide band color demodulator set like the 21-CT-55?

No, for all intents and purposes it's a CTC-4 as far as demodulation is concerned. Only thing borrowed from the 21-CT-55 is the horizontal output transformer.
