My "new" 1954 CTC2B 21CT55 21" roundie

What is the RCA in one of your pictures that is to the right of your find? Looks like a '58 or '59 model??

Or do what I did and break apart any octal tube to harvest the socket, and use that as your B+ jumper. All you need to do is connect the appropriate pins, and you'll have power to all the circuits. Just make sure you NEED power to all the circuits! It works on all the early CTC chassis.

The other roundie is a CTC9, model 210CK924. It looks pretty good, but still needs some work. Set has low hours and has the original 21CYP22 CRT. Right now (as of yet) it is running with the original filter cans, which I still intend to replace with modern caps, although they do run fairly cool. It still has a problem with the vertical and horizontal sync at times, and the vertical height has a tendency to collapse. (I believe there is a broken ground somewhere on the vertical/horiz circuit board) Cabinet is in perfect shape, no scratches, back and everything is complete and the set when I got it was super clean inside for it's age. I obtained this on Craigslist from Blair NE. I have another post on here somewhere about the set.
