two references should provide all the detail you will ever need:
K.K. Clarke and D.T. Hess, _Communication Circuits: Analysis and Design,"
Addison-Wesley, 1978.
W.A. Edson, "Vacuum-Tube Oscillators," Wiley, 1953.

Subject: HomeMade Radio
I am interested in building a radio completely by scratch (not a crystal
radio), including building my own vacuum tubes, etc. Does anyone have
plans for such a thing. I want to try to stay as close as I can to early
designs. If you have any such info or plans, please E-Mail them to :
MMSDC@aol.com
Thanx!

Subject: Looking for Tower plans
I am looking for plans to construct a homebrew antenna tower.
Either that or a pointer to a reference manual that would
contain that type of information. Please post your information
for the benefit of others that may be interested.
Thanks,
Mike
