Default Re: Most Minimal Superhet

Aside from the ingenious reflexed versions of short superhets I posted earlier (which didn't attract many remarks) good performing short superhets have been designed & built in Australia since the 1940's, without reflexing.

The classic was "The Little General" In these radios they did not reflex the audio through the IF and used a 6V6 which helped. See attached image.

The Little general was again introduced over the years in the 1950's & early 60's in a number of variations with other valves and a 6BM8 as the output valve and ferrite antenna added. They were intended for home construction.
