Got some weird kit tv????

This one was interesting. Spotted it at an estate sale on Friday (took a couple vacation days) but went back today on half-price day knowing it would still be there. And yep, it was. Got it for almost nothing

Pretty sure this set was a kit of some kind, but more accurately it looks like something used for classroom instruction on TV repair. Every control, every tube, etc is clearly labeled, even on the underside of the chassis. Picture tube is a 19GWP22. Even got a screen mask for the picture tube.

Powered up on a variac, it gets full sound, but almost no vertical sweep.....probably needs a standard recap. Lots of black cats underneath. But man this thing is built well. What it is exactly, not sure. What I'm gonna do with it, same answer

Looks like an RCA yoke housing.
Hows about a few part numbers off some diferent things & maybe
we can ID it. Looks like nothing I have ever seen.
Nice find......

Build a plexiglass cabinet for it maybe? That'll make it stand out.

Couple more. See how it's labeled underneath as well?

we had a 17" ge color yc chassis i believe with a plexiglass back. and extensions on the back of the plug in modules for making trouble so we could see the trouble and figure it out. that set played all day every day and had one of the brightest and sharpest pictures i have seen on a tv set from that era. it would have been a 1977 or a 1978 model. i would have loved to have that set i am sure it has been long gone for years.

this was a 2 year vocational college course i attended. tv
& radio repair

The pincushion transformer looks an RCA design too. I'd go over the tubes used and go from there to see what's similar. I'm not saying that it's an RCA but the circuitry may be derived from "patented" RCA designs..

It does an institutional look to it for sure. Interesting piece!

Ain't that the truth.

The wiring underneath the chassis looks to be very clean and pristine for an older set - especially one from the tube chassis era. Most of the wiring in sets I work on it dusty, dirty and often cracked and slightly melted.

Are any of the circuits labelled on the chassis? It certainly looks like something used for training purposes, though could alternatively just be the product of a very thorough home handyman. I always label the tubes on the chassis when I work on a set, and if I were to build one from a kit, I know I'd take the time to properly label all the tubes, connectors and controls to assist in any future repairs or adjustments.

That last picture you posted? It increased your Internet Respect Points balance by 1500. I doff my hat to anybody who actually rocks out in a workshop that has purple walls. Actually, it looks like you fed a "violet" color band from a resistor into the magic pigment-my-paint-this-color machine.

This tells me that the builder of this set owned a label maker and this set was made to be easily and quickly repaired.

This set reminds me of Johnny Cash's one-piece-at-a-time car, in that the building style reminds me of an early 1950's Conrac monitor, but the parts obviously are from the late 1960's or early 1970's and hint RCA design. I cannot understand why he wired the sweep with green hookup wire and the video with red wire.

Except for Heathkit, I do not remember any other color TV kits during the probable era and this is unlike the Heaths.

With that said, the best potential clue may lie in who built the printed circuit boards.

I noticed a couple of caps that seemed to be just tacked in and not properly mounted. Could this be a testing prototype for a limited run custom production, say a military or NASA contract?

Heh

My whole basement has purple walls. I keep all of my television madness to one room. And right now, the sucker is PACKED, much beyond my comfort level.

I put that old kitchen rug on top the Zenith roundie so the cats wouldn't try to jump on it and slide off and use claws to try to gain traction, but now it's their favorite place to sleep. Oh well.

And yes, that's only one angle
