  • The General Electric 105 is an AC/DC operated 5 tube BC band receiver.  The BC band frequency tuning range is 540 - 1600kHz. Has built-in loop antenna with provisions for connecting an external antenna.

    The following models use the same schematic and chassis but have different cabinets:

    Model Cabinet
    100 Brown Plastic
    101 Ivory Plastic
    103 Mahogany Wood
    105 Maple Wood

    Note 1: The advertisement in the March Radio Retailing magazine (on page 37) listed the model 105 as having a "Solid mahogany cabinet in blonde finish", however Riders listed the cabinet as being Maple and pictures of actual 105 radios also have maple cabinets.

    Note 2: The following production changes were made on models having serial numbers of 5000 and above (Per Riders and Beitmans):

    a)   C18 connects between the output tube plate and screen instead of the plate and ground.
    b)   The plate and screen filter (C11, R6) is moved from the IF amplifier circuit to the converter plate and screen circuit.
    c)   The filament connections (pins 2 and 7) of the 12SA7 converter tube are interchanged.

Discussioni nel forum su questo modello: General Electric Co.: 105

Argomenti: 1 | Articoli: 2

I'm trying hard to find the right pictures, date and data for the model pages by scanning and uploading pictures from the monthly journals "Radio Retailing", later called "Radio Television Retailing". Most of the work is done by my daughter and today she confronted me with the model General Electric 105 when scanning the March 1946 issue on page 37. The present picture on our model page for GE 105 showed quite a different picture - a plastic cabinet with two big knobs on the middle of the front. When clicking above for this model, you will see that now it is showing quite a different model - with a scale in the middle between two ordinary knobs.

What is the story to this?
I left the old model page but changed the name from 105 to "105 (Radio Attic)" - because that picture was supposed to be uploaded by Tom Voegtli to Radio Attic. Our uploader, Hans Amberger, got the right to copy it. I checked now that page and saw: Yes, it is there as GE 105 in this cabinet - correct for 1946. In Tom Voegtli's Attic I could not find it, but here again. We all are not perfect, and I believe this model is not a GE 105.

The facts:

As you can see on the new page for GE 105, SAMS photofact date October 1946, set 466, folder 13 shows the technical details - all the same for GE 100, 101, 103 and 105. The title page presents the photos of model 103 and model 100 (right) only.

The "Collector's guide to Antique Radios, 7th edition" does show a photo of model 100 and mentions data for it and for 102, 102W, 103, 106 etc. but nothing for 101 or 105.Mark V. Stein does not publish them in "Table top radios volume 1". "Grinder's directory" lists them all - as plastic radios. "Bunis 4th edition" lists the 103 as wood (correct) but not the 101 and 105. Stein's "Machine Age to Jet Age II" does not bring them. I could not find a GE picture of that face of a radio, nor did I find it in our picture gallery of more than 1000 models with picture(s) of GE radios ...

Radiomuseum model pages:
Model GE 100: Several pictures including an ad in "Radio & Television Retailing" January 1946, page 11 with pictures for the model 100 and 103 under the title "Praise from everywhere". We can actually assume that this entered the printing house well before Christmas 1945 and one could argue that those models are from the season 1945/46! No prove yet, so we leave it as 1946.

Model GE 101:  We show the schematics but not yet a picture.

Model GE 103: We show the schematics, the SAMS picture and the mentioned ad (see 100) with picture.

Model GE 105: We show the schematics and a PR article from "Radio & Television Retailing" March 1946, page 37 with a picture. The text of the article reads: "Model 105 is a deluxe 5-tube ac-dc superhet. Receives on standard broadcast band. Decorative grill is of multi-weave burnished metal. Felt feet on base of set protect p9lished furniture tops. Solid mahagony cabinet in blonde finish. 13" wide, 8 1/4 high, 7 15/16" deep. The article goes on with a model 111. We show a Beitman schematic for it - including the model 110.

Conclusion:
Since we build up the most complete reference work for radios and related, we have to show this model page "105 (Radio Attic)" and explain the facts there (at least as long that such a prominent site as Radio Attic shows this picture for a GE 105. And we have to bring that picture to the right model too. Therefore we hope that a guest or even Tom Voegtli can tell us more - using the contact form.
