I haven't checked into that problem yet.. It seems to be working for the most part.. If the problem is there, I just tap on the bottom of the set and it goes away.. I don't have the room to pull it out and look into the issue..

I touched up all the tube sockets, but solder joints on this GE were not bad, certainly better compared to an RCA with more hours anyway.

edit- Picture in my newly constructed shop. Unfortunately its very dusty right now, but nothing beats watching an old movie while you're installing base molding, etc.

I remember the GE sets at a local appliance store I used to haunt. Never had the chance to work on one of their large color sets, but I do have a couple of Porta-Color sets. Yours looks really good ! I'm wondering if GE ever used an RCA clone chassis, seeing how they used some different circuitry, especially the crystal ringing circuit for the chroma phase reference instead of an oscillator. Works very well in my portables.

You have to wonder why more manufacturers didn't jump on the shock-excited crystal chroma phase circuit. There has to be some major disadvantage compared to a PLL, but I can't seem to think of one off the top of my head...

You mean the first 21" GE roundy right? They had a 15" set in 54 that used the same osc-less chroma ref circuit that GE was later known for.

Another me-2 color set seen only in a SAMS, Model 15CL100? I recall a thread.

The CA, which had a 6BHll and 6FM7 and a few other 12-pin tubes in place of the familiar RCA types, it was basically a CTC15 clone.
CRT was labeled GE made by RCA just like this set. Before the CA was the CY-FY, before that a chassis CX (CTC12 clone) and the best of all IMHO, the 1962 models with the CW a direct copy of a CTC11.

I really do not think GE had better luck with flybacks than RCA though.
