GAROD TELVISION Project
 
5 Attachment(s)
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.
Ed

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.:scratch2:
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's an interesting TV. Hard to tell exactly from the photo, but it looks like the tuner might use air variable capacitors, similar to what you'd find in a "boatanchor" communications receiver. I have only a couple of TVs with that type of tuner. (It looks like your tuner might also be missing a side panel; they are often enclosed in metal for shielding.)

Your cabinet is finished in lacquer, not varnish. I would try to "revive" the finish rather than strip or sand it down to bare wood. In short, touch up the worst spots and then apply some new lacquer. If you strip it, you will lose all of the decals around the front controls, which could be hard to replace.

For mold, I'd start by scrubbing out the inside of the cabinet with some hot soapy water, maybe with a little bleach to keep it from coming back. Dry thoroughly. Mold should not be a big problem in the future if you clean it carefully now and then keep it in a dry environment after restoration. The heat of normal operation will also help keep it dry.

Phil,
Tonight I started cleaning the cabinet with water and bleach. With a lacquer finish, is it safe to lightly sand the cabinet? Are all lacquers alike? The finish cracks are quite deep in some areas. I washed the double pane safety glass and CRT mask.
The set does have a General Instruments ganged split capacitor tuner with
three 6J6's.
I'll have to look through my Sam's folder's to see if this set is wired for "Tele-Zoom " Tim.

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

Unusual Capacitor in Garod 1244G
 
5 Attachment(s)
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.

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....

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.

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.

Starting to look good, cool hard to find set!

The other night while shelving some sam's folders, I noticed Set 99A has a schematic of the Garod 1244G series sets in it. It's in folder number 5. I looked in some of my Photofact indexes and not one of them lists the Garod 1244G series chassis in 99A-5. The schematic in set 99A-5 is indentical to what I found in the Garod 1244G I recapped/repaired. There are no wiring errors like the Riders has for this set.

Just more pictures. I still have to find some knobs. The knobs on the
station selector might have been on the set when I got it ?
