Well the 3DS3 that came with the set is actually a good tube now that it's socket has been rewired wired to supply it with filament voltage (go figure
)....Found this out late last night and did not bother to post.
I had to clean the tuner and coax the fine tuning slugs out to a position where it would tune stuff, but it works decently.
The CRT tests weak, but it was able to produce a picture at 10KV yesterday, and does not substantially improve with a brightener so it is what it is.

I adjusted color, tint, screens, drives, red and blue demodulator balances, and despite color improving and being fairly watchable, it still don't feel quite right....Did those resistors have an effect on the color matrixing?
It feels like an overgrown hybrid Portacolor, and has seemingly worse color than the best portacolor I've owned....Sound is surprisingly nice though....Seems someone thought well enough of it to add an RCA jack connected to the speaker.
Think I may still pop $5 on a correct schematic for it just so that if I ever put it in regular use somewhere, and decide to go through the color circuits with a fine tooth comb, I can.
Here are some pictures of this PB/Teledyne badged C2....It seems to be a low hours set...PCBs are fairly clean, and all the tubes are GE (most blue label).
