Got some weird kit tv????

[Eric H]

The knobs look a lot like the knobs on this NRI Conar TV kit:

Me thinks the Conar is a Heath Kit.

The labels look pre-printed, not something you would do yourself with a Dymo labeller or rubber stamps.. So I'd guess this was a limited run meant for instructional purposes, maybe for trade schools, maybe even made BY a trade school. Remember all those old ads in 1960s electronics magazines?

[Jeffhs]

NRI was the National Radio Institute, a trade school of the 1960s. Their ads appeared quite often in magazines such as Popular Science, Popular Mechanics and one or two others. This color TV was included in one of their TV correspondence courses, although I don't recall ever seeing the cabinet included with the set. IIRC, most of these correspondence-school TVs were offered as the chassis only, meant to be installed in a custom cabinet or wall mount. Heathkit also had several TV kits for which the cabinet was optional, but was available directly from them for an extra charge.

Did just a base recap of the set, not including the filters. No change. No vertical sweep....the 6GF7 is still dark, and that's the key to the whole issue here I think.

Now, since I don't know what this set is and nobody else does either with any certainty, suggestions as to where I should go from here? I can do the filters, I just don't feel like it if that won't cure the issue

Normally right about now I'd start testing chassis voltages, but God only knows what this TV even IS to try to get a schematic for it.

[IsthmusTV]

Why don't you see if you can restore filament voltage to the 6GF7 and go from there? It shouldn't be tough to trace out even without a schematic.

Good luck, it looks like a fun project!

[Kamakiri]

That's kind of what the capacitor replacement was about. There were a whole bunch of black beauties in that section that I replaced.

The problem is, in part, that I have no way of knowing if everything is even hooked up correctly or if there isn't something missing. Who knows if this set EVER worked.

Fun? Pfft. This is ten dollars worth of television hell

Well, for sure you need 6.3 volts on the heater pins of the 6GF7 (Pins 4&5) perhaps a wire is poorly soldered or missing, or the tube socket pin is broken/corroded. I would get some juice to the tube heater and see what happens.

Ditto that

Hows about a few chassis pictures ? Maybe we could ID it.
Could be it never worked, not rare on kits. We wouldnt
touch one even if it worked fine. Definitely get the
6GF7 lit up before doing anything else. Oh if its on a PCB
watch for poor grounds too. Usually where the PCB solders
to the steel chassis.

I'll do that in a couple days. Out of a clear blue sky, my two boys, ages 11 and 14, have decided they want to get into TV and radio restoration like their dad and seem to have a voracious appetite for it. My 14 year old just recapped a Bendix 636C radio, and my 11 year old decided that he wants to take on restoring this Admiral 10" console that I was going to use for parts. I gotta say, these kids have some soldering skills....their work is pretty darn neat

We'll see if this lasts, but based on the last week, it just might. I think they're burned out of video games and are looking for a new outlet. Nick, my 11 year old, soldering iron in hand, said "you know Dad, now I get why you do this. This is FUN."

There were a few Tech Schools, like the Conar, advertising kit TVs.
NRI in Scranton and Bell and Howell in Chicago.

Once it works, an RCA design that is hand-wired has to be an improvement.

There is a good TV repair quote if I've ever read one.

That's cool that the kids are wanting to get involved! My interest in TV and electronics came form watching our TV repair man(who was a family friend0 work on our CTC-40 (normally a bad power switch, and a UHF tuner or two as Youngstown has no VHF stations) Next get them started on old cars
