General Radio

Hey can anyone give me some info on the old General radios? I recently talked to a guy in New Hampshire, and he was talking on one. It sounded phenominal, like broadcast audio quality. All he ran for a mike was a non amplified D-104. I was blown away! I know nothing about those radios and want to learn some more. I may be on the hunt for one sometime soon.

They were well designed radios what do you want to know about them?

Were they strictly a transmitter? Were they a small radio, big, really big? VFO or crystal selector for channels? Sorry I'm asking dumb questions, but I'm really curious about these. What did they usually do for power?

The one I had was a General MC11 if I remeber correctly it was a 23 channel transceiver using a crystal mixing circuit and was all tube and about the size of your Browning receiver or transmitter.

The speech amplifier was a 12AX7 can't remember what the modulator tubes were but it used a phase inverter driving two in push-pull.
The final was a 6GE5 which was capable of 20 watts input if the screen resistor was changed to a lower value which is why at the time that rig was very popular.
I remember the receiver used the new type Nuvistor tubes in the front end.

General Radio & Telephone was a manufacturer of business band radios at the time and the cb line was well designed and built.
I think the cb's used the same circuit as their business band radios that operated above 30mhz only the voltage on the screen of the final amplifier tube was reduced to keep within the 5 watt input limit.

Thanks for the info Crawler. Is it true they had built radios for the military as well? Someone once told me this, but I can't confirm that it is correct.
