GE 12T1 CL find

There's possibly a good 10FP4 in there.

It's a 12" set, 12LP4 most likely.

Ah! So that's probably why it's 12T1.

It looks like a replacement CRT in there! The original was a 12KP4, no ion trap and aluminized.
When working right and the original CRT, they had an amazing picture.
IIRC, they had the 41mhz IF, very early. Quite an advancement.

Yeah I see now that the Wisconsin CL set has an Ion trap. I'd forgotten about the 12KP4. Apparently GE developed both the 10FP4 and 12KP4.

It's a 12LP4A, NVC branded (National Video Corp). Tube looks good, no burn in. I have to find out the hard way whether it's bad or good, since I don't yet own a CRT tester.

I went out and purchased the set in Wisconsin today, since it was only a 20 minute drive from my house.

It's going to be a work in progress. It powers on, no raster, but it gets sound and gets signal with loud and clear audio, so all that is working. I probed the anode and it's only producing about 2kV, so it needs caps, and some adjustments.

Great to see someone got the WI set. Now you and Eric can compare notes.

Yeah him and I can cross compare notes. I'm probably going to make my own thread as to not hijack Erics.
