CTC-20C for the record

Interesting set,

I've seen old ads somewhere of $495 specials for lower end roundies. I doubt this was too thrifty, NICE cabinet quality. Dial and benzel very similiar to early RCA SS. This is a unique transition piece before ss.

DOES this have any ss components??? It only helps with reliability.

Not really except for diodes in the usual places: LV and B+ Boost rectifier, detector stages. But it does have a transistor in the UHF Tuner which had become standard practice by this time.

These sets were produced around the 1966 timeframe. This one that I have has date codes of 66-30 on the CRT and the tubes were earlier . The Howard Sams was published 9-66 as folder 837-2.

My idea for rewaxing flybacks is to remove the tire, submerge the coils in a pressure cooker full of molten wax, put the lid on, pull the pot into a deep vacuum for a few minutes then slowly release vacuum remove lid and coils and let cool. That should get all the air out of the coil. Its basically how the factory does it.
I dont care if its dangerous, Ill do it outside with the proper protection.
