Stupid question about CRT swaps??

[Chad Hauris]

The later chassis round set was a CTC-20. I have one but have not got around to working on it yet...it actually has a CTC-31 chassis minus the pincushion components rather than a CTC-38 chassis. According to my book the CTC-20 was produced in 1967 or 68. The CRT faceplate and controls look exactly like the most common type of CTC-16 set.

The flyback circuit and vertical output transformer circuit are slightly different among the two to accomodate the pincusion components in the CTC-31 chassis but the rest is the same.

I put a flyback from a Hoffman CTC-17 rectangular clone set into a Silvertone CTC-15 clone round set one time and it did work but the width was a little low. All of the flyback connections were the same as I remember.
