You're gonna be busy replacing all those wax caps. And electrolytics. I have a similar set, a 24R12. Found that its vertical nonlinearity was due to a bad electroytic bypass cap in the vertical output.

Nice complete unmolested set. Cigarette Smoke tar makes for a great cosmoline substitute.

I went digging through the Admiral 30A1 chassis (Rider TV3) and found the cabinet styles

30A12 - Walnut
30A13 - Mahogany
30A14 - Walnut
30A15 - Mahogany
30A16 - Blond

Very, very nice set. I am glad that it went to a good home. Admiral sets should be an easy restoration. You have lots of caps but when you start at one end and move along to the opposite corner, first thing you know, it is all done. No real odd ball values there either. The chassis is somewhat similar to my 26R16...

Good info to have. Both the A12 and A14 are Walnut?

I have all the caps and parts I need for this one, but it's going to be a few weeks. I'm elbows deep in my Admiral Tele-Bar restoration.

Hi mbear2k:

I saw your Admiral posts and joined the forum right away! I was given a 30A15 yesterday, found on a street corner in an old neighborhood in Lowell, MA. Mine has channel 1 and a wafer tuner with 3 6J6's and no balun. I guess that it's the 1947 model. Uses two 11-pin keyed plugs for the power supply chassis; those are missing, as someone cut 'em off.

Thank you for the very nice photo inside the main chassis. It is helping me to identify some missing caps. Looks like the set was hacked at during some ancient attempt at repair.

BTW, congrats on the beautiful condition (mine has a bit of rust). How's the restoration turning out?

Interesting - I'd heard there was a version with channel 1, but I've never come across one.
You can get the service info for the 30A1 chassis here: http://www.earlytelevision.org/tv_sc..._diagrams.html

I have a 30A12 and 30A16 if you need any more reference photos.

Channnel 1 Admiral 30A1

banderson: Wow. That's quite a beautiful collection. I've never seen a Dumont with 2 tuners on it. That set does not look quite old enough for UHF... is that's what's going on?

FYI channel 1, here's a photo of the tuner with the channel 1 coil set at top, channel 2 showing at bottom. The design looks fully balanced through the mixer, with six coils for each channel. The shield (removed) is riveted to the IF shield, bent out of shape by some repairman/felon.

Also note the 11-pin headers on the power chassis. The recepticles and harnesses were cut off. Eleven-pin Amphenol plugs will be fun to find.

I'm a bit baffled by that ETF site. The 30A1 chassis is listed but the 19A11 comes up instead. Please tell me I've turned the wrong knob.

Cheers!

Thanks, but I don't own any Dumonts - which set are you referring to ?

Wow, that tuner is very different - all of my Admiral sets have a drum instead of wafers.

I see that your power transformer is oozing wax just like my 30A16. I was worried that it was a bad sign, but maybe it's normal ?

Yes, the ETF link does seem to be wrong. Here's the correct one: http://www.earlytelevision.org/image...-rider-tv3.pdf

Oops: That Dumont was under your flickr photo favorites, now I see it belongs to matt_s78mn. Sorry.

Thank you much for the correct schematic link, I'm now well fixed to begin bringing that Admirable back to life.

Mike - congratulations on your find. I have yet to start on mine. Working on an Admiral Tele-bar first. Your set is interesting with that tuner. Let me know if you need any pics or detail that I can help with.

Mark

I was browsing eBay just now, and saw a listing for a red "K-Mart" branded 12" b&w portable TV in the Detroit area. At one time in the '70s, I believe these little sets were made by Admiral for K-Mart -- the control panel looks like one I would expect to find on a '70s vintage Admiral portable TV.

BTW, I live in northeast Ohio near Cleveland and don't see too many old TVs, even in the trash. The last small portable I saw here, ten years ago, was an RCA 12-incher from about 1980 -- on a curb very near my apartment. I've seen an RCA ColorTrak console set from '78 and a couple of stereo consoles since then, but none recently. With the DTV transition in June 2009, I was half expecting to see old (and not so old) analog b&w and color sets on treelawns and curbs all over my small town, but it didn't turn out that way -- not even close.

Here's yet another one! I thought these were fairly uncommon

It's a bit overpriced for the condition, but all those pictures are a fantastic reference. I've saved them all to my computer.

I can't believe someone cut the umbilical cord


My cabinet was stripped down (decals and all) and refinished in a light two-tone polyurethane.


Looks like the tail broke off the channel knob. I wonder what that hole is for - aligning the tuner coils ?
Mine doesn't have one and neither does Mike's above.
