GAROD TELVISION Project

[EdKozk2]

Hi,
I posted some pictures of, I think is a Garod 1244G or 1244T television. I've had it sitting around for 20-25 yrs. The 12LP4 crt and high voltage were ok
when I tested it back then. Any idea's on removing mold and stripping varnish? Sam's 93A-7 , Sam's 60-12, and Riders' 3-8 Garod have the schematic variations for this set. Anyone ever see pictures of this set before? I haven't found any for this model. I hope to have this set working by
the end of the year.

Just some more pictures of the Garod 1244G or T.

Nice find. Garod televisions are pretty scarce.

I can remember where I found or got every old B&W roundie set I have, except for this Garod. I don't remember where I got it.
I thought there would be a lot of Garod sets in the New York area, since
they were manufactured around NY.

Even here in NY it's an uncommon brand of TV. I can recall seeing only one or two in the past.
The choice model is the 930. Very unusual early post-war model. I'd say about as rare as a pre-war set:

I saw the 930 at the ETF Museum when I was working in the Columbus area about 3 years ago.

NEVER have seen one "In Poison", & PRECIOUS few pics of 'em are available.

Tele-Zoom was a feature that Garod marketed on some of their porthole sets. The picture could fill the whole round CRT or be shown rectangular. It was like the "Opera Glass" feature on Stromberg-Carlson and Zenith "Giant Circle" with "Picture Control" switch. The difference is that Garod supplied a single button wired remote in a catalin holder to activate the function.

That is not a Tele-Zoom model, but still pretty unique with the slide rule dial.

I',m in the middle of recapping and found a .05mfd paper cap wrapped in foil.
The foil is grounded. The capacitor is connected between the cathode and
screen grid of the 6BG6 horizntal output tube.
Anyone ever see one of these in a circuit before ? Is the foil a shield from the
high voltage, 10kv 500mmf filter cap ?
This set is a 1244G model for sure. It's in the Riders 3-8 Garod. I have found a wiring error on the schematic for the secondary of the vertical output / yoke connections. The yoke should be grounded, not connected to the 360 volt B+ line. Caught this error comparing Sam's 1244T schematic, folder 93A-7 to the Riders 1244G's.

You run across these shielded caps in old radios once in a while, although I haven't seen one in a TV before. The usual approach is to replace it with an ordinary modern cap and then evaluate how the set works. I believe most people find it's not necessary to replicate the foil shield.

If you want to shield your new cap, you can get copper foil at a hobby store. Or you might be able to salvage your old foil and reuse that.

Phil,
I remember seeing a few foil wrapped caps in few radio's I fixed years ago too.
I'm finding that over half the resistors in this Garod 12444G are 50 to 100 percent out of tolerance. I've been replacing them as I progress.

If you use those yellow plastic replacement caps don't solder the new shield while it's wrapped around the cap. If you do you will melt the insulation the, metal foil, and dielectric of the new yellow cap ruining it.....I've killed a few of those caps by accidentally touching a soldering iron to the body of the cap....

Tom,
I never used the plastic yellow caps, yet. I'm still using caps I bought in the 90's. As for electrolytics I use new ones, not more than a year or two old.

These are some pictures of my progress on the Garod 1244G chassis.
