I notice that the tuning cap doesn't move much when the dial is turned. Usually these caps were shock mounted or isolated with screws and spacers run through rubber gromments that lined holes in the chassis. This one looks like it was solidly and directly mounted to the chassis.
If the radio was not a kit sold by Heathkit, one might be lead to believe that the transformer had been replaced, because Stancore used to mark their replacement transformers with bright yellow labels like that. Does the label say Stancore?
In addition to the filament winding, this is power transformer undoubtedly has a high-voltage plate voltage winding and possibly a separate rectifier tube filament winding (especially if the rectifier does not have a separate cathode).
@CampKohler Maybe someone can identify this radio. the video was shot 2 yrs ago and the artifact itself is buried somewhere in our storage so I cant get details.
@EdisonExploratorium There is no difficulty in identifying it. At 0:56 you can see that it is a Heathkit BR-2, Some of these kits were available assembled (at a higher price of course). As soon as you could buy assembled and working electronic equipment from China (or elsewhere) for less than American companies could buy the parts, Heath, Eico, Allied Knight and all the other kit businesses bit the dust if they did not have other ways to make money.
