Will do, here are some more pics. The flyback looks pretty new. Looks the flyback was made in 1980, as evidenced by the two digits after the "274" engineering number. (think this doesn't work?, try it out! I learned it from an old RCA tech). The tuner is a confusing array of soleboids and motors, gonna clean up this chaasis and bench test it! -Rb

Hey Rob, I just got a CTC-17 combo as well. Did you bench test the chassis yet? My set looks like yours except the tuner and controls are in the stereo bay..

So how do you work on these bigger sets to trouble shoot and do tests and such? I was looking at my 64 roundie Zenith and you would have to have a crap load of extensions so you could put the chassis on the bench. Or can you normally access most test points easily from the topside of the chassis while in the cabinet?

They did make a test jig (13" and 19" screen sizes) that were designed to enable a chassis to be removed from the cabinet and tested on the bench. The test jig usually had a wide array of adapters and cables to fit the various chassis of the day. I don't own one of these; but, I'd like to. It sure would make working on console TV's easier.

Um yeah, ditto that.. What I manage to do and its not easy but it works for me is I made a wooden structure that will house the CRT to bolt up to. This structure is bolted to my bench. There I have the neccesary room to work on the chassis and see what I am doing. I makeshifted a grounding strap for the CRT to chassis. The only thing that is whacked about the whole setup is the yoke wiring on some CRT yokes are too short and of course the usual anode lead only being a certan length make moving around the chassis a chore cause it's still the same problem with the CRT being in the way but it's alot easier.

That gives me an idea...I have several dirty old 18" RCA's-I could save one as a test jig. I used to have a 21" round tube jig, that I maybe should have kept intact, but it was such a space hog that I might as well have stuck the whole set on the bench! (it was basically a metal table model CTC-11 cabinet)
