Stromberg-Carlson 761
Made in Toronto, Ontario, Canada
ca. 1947
This was one of three parts sets in a single eBay auction.
The plastic dial cover and grille cloth are in excellant shape. That bit of masking tape on top was a label that said "No speaker / poor sound".
The other two sets were Stromberg-Carlson model 561, which has a nearly identical chassis.
One of the 561 chassis will provide the missing audio transformer and speaker.
At first I thought the dial face was identical to the older style dial face of the model 561, but when I was taking this photo I realised that while the green graphics and numbers matched those on the older 561 dial face, the lettering in the logo was the newer sans serif style. The dial pointer is identical to that on the 561.
There is a model 1100-H, shown in the Radio Attic archives that has a cabinet that looks exactly like a 761. That one has a dial face that looks more like the older style for the 561 (green outline, serifs on the logo). I don't know yet if there are any differences in the chassis.
All 761s that I've seen have knobs like on the 561 (below left):
My 761 didn't come with any, so for the time being I'm going to use another type of knob (above right) seen on several Stromberg-Carlson sets from that era (including the model 1204. I have a few spares of this type. It's not really authentic for the 761, but at least it's in the right family, and as near as I can make out they're what's used on the 1100-H.
