John, your email system is rejecting any email I send :(

Amps List ..

I have started putting together a website where I'm putting
my 30 yr collection of electronic print on. Its not organized
in anyway, that will be done this winter.

I'd love to have a copy, and would put it on the site for anyone
to see.

I was looking through some old GE REVIEW periodicals and found a set of 
well written articles explaining the theory of vacuum tubes as they knew 
them in 1927. Turns out they knew it pretty well, including Thoriated
Tungsten filaments and oxide coated filaments. They didn't talk about
screen grid tubes  but did talk about groups of damped waveforms, i.e.,
radiotelegraphy at the time. Amplfiers, HF Oscillators are discussed.

I don't have a place to post the scanned documents here, but I can email
them to interested parties. Its in 2 parts, in 2 and 4 Megabyte size
roughly. THEORY AND CHARACTERISTICS OF RADIOTRONS Parts I and II, by L.
Koller of GE Research Lab and H. Schroeder of the Edison Lamp Works.
