Paul,
Do you remember the Ladybird book of how to Build Your Own Transistor Radio?.
Back when you could get bits for radios.
I have a question for the ECN family here, is there still a company that makes Air-spaced Variable Capacitors and Trimmer capacitors as well?.
I ordered 3 212pf Double Gang Capacitors in the late 1970's from E.F Johnson Co and never recieved them.
I saved up from my after school job NZ$49 (1979) got a money order (that in itself cost $12) and never heard a bean since.
I was under the impression the Postal service here had taken my money.
The tuning cap is the most hard to get part of a radio these days.
Doesn't anyone make this sort of thing anymore??.
