I just picked up this 5-tube Coronado from around 1960 and am trying to figure out who made it. It's a model RA 48-8257 and their is an EIA source code of 786 printed on the label. Next to the EIA code, there are the letters "HGRC".

This is a standard AA5 radio with a phono input jack. It is built on a metal chassis and used several wax paper capacitors. By 1960, I thought most everyone (except Zenith) had switched to PC boards. I also thought that everyone was using those RC component combinations by that time, as well.

This radio uses a 6 1/2" speaker and I think it was considered a "hi-fi" model, as far as AM table radios go. After a recap and a new speaker, it performs well.

Meteor Transformer Mfg, Detroit MI ?

Coronado was a house brand marketed by the Gamble-Skogmo stores and built by various manufacturers. Some of them were Belmont, Wells-Gardner, Kingston, and Warwick. By around 1960 not sure how many were still suppliers and there could have been others. Can't think who HGRC would be. It would be nice if it were WGRC since it would be Wells-Gardner. Does it look like it could have been an import?

HGRC= Hinners-Galanek Radio Corp. Their brand name was Cavalier. I think they were absorbed by Esquire, or some other east coast firm.

Dieseljeep, great info. Is there a common source for those more modern manufacturers?

Thanks for the information. That's a company that I've never heard of.

There's another company that made Gamble's radios. Eckstein in Minnesota. They made mostly car radios.
