Hello From Edison, NJ

Post by Spock1 on Wed Apr 25, 2018 11:54 am

I have a extensive collection of old time radio programs and am now interested in understanding the underlying tube technology.

1. How was the Flemming Valve, i.e., diode used in early radios.
2. Same question on the triode introduced by De Forest triode.
3. Does anyone have circuit circuit diagrams for both TRF and Superhetrodyne Radios, with, if possible explanation of flow through the respective circuits.

Any help greatly appreciated,

Otrman (Henry)

If you can get a book called '' The Elements of radio'' by Marcus and Marcus, it will give you all you need.
When I started to restore radios I studied it because I didn't know anything about how a radio worked.
It starts from the beginning and most of it is in layman's terms
I find that many others recommend this book.
I also believe you can get it on line but I am not sure where.
