So this is a previously unknown set?

It's in SWEET condition!!!:banana:

Should we do a poll on how much it'll go for?

$5,600 already with just 4 bids!!!! This one is going to be fun to watch.

You have fun watching the auction, I'd rather have fun watching the set!

What a beauty. HM-225 is just about my favorite of all prewar sets.

Quite a transformer in that nice ol' beast.

This is a newly discovered set.

That is a great set in superb original condition. Does this set use electromagnetic deflection? It looks like there are yoke wires going to it. Do you suppose it had a back cover originally? Many radios from that era did not. I wish we could see the labels on the front panel controls. I would love to read the schematic for this set.

It uses electromagnetic deflection. Most 9 to 12 inch prewar sets did. Electrostatic deflection was used in the 5 inch models.

It did have a back originally.

Here is a page about the restoration of the HM-225 in the Museum's collection:

There are links to pictures of the chassis and a list of tubes, etc.

We haven't posted a schematic on the site, but here is one of the RCA TRK-12, which is similar:

Steve,

Let me guess... Somebody stumbled upon it and got the set for nothing? Now they are selling it for big dollars on Ebay. I do not fault them for doing it if this is the case. If it were me I would keep the set till I died.

I'm on the sidelines for this one... too much money for me.

Looks like its in my neighborhood, but not my price range.
Going out on a limb, probably made at the GE works in Schenectady and has been in some former GE engineer's attic for oh these many years.

Technical question: given its vintage, would this set be NTSC-compatible if restored to original specs? Or would some sort of conversion be required to get an image on this (presumably 441-line) set?

It is a 441 line, AM sound set, but they work just fine on NTSC with little or no tweaking. The manufacturers offered to set these televisions up for NTSC in 1941 for free to the owners.

Nostalgia Air has the HM-225 schematic, (http://www.nostalgiaair.org/Resources/068/M0008068.htm) have had for a very long time in fact.

Thirteen grand with eight hours to go!!

Bidder 6 bidding activity seems funny to me. He bid on 24 vintage electronic items in the last couple of hours. Seems funny for an eBay user with between 10-49 wins total? ???

:jawdrop: :jawdrop: :jawdrop:

Holy Merde ! $24K ! An' th' damthing wasn't complete...Sheesh....

When I clicked on the auction link this morning to see how it came out, as it was loading, the phrase "over twenty-thousand" went through my mind. I am not one bit surprised.
