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: http://www.earlytelevision.org/ge_hm...storation.html 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: http://www.one-electron.com/doc_archives/TRK12.pdf |

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. polaraman

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.
