Do a web search on tube receiver (on Altavista I do +tube +receiver, which
finds only things with the word "tube" _and_ the word "receiver"), then do
another on glowbug receiver (+glowbug, +receiver). You'll find _lots_ of
stuff. Looking for regenerative receiver will also net you some interesting
info.

Lindsay Technical Books (http://www.lindsaybks.com) is in the business of
finding and reprinting interesting old technical books, they have some good
titles including ARRL handbook reprints from 1929 and '35, as well as at
least one book specifically about regenerative receivers.

I'm looking for a simple 2 or 3 tube receiver schematic, regen or
otherwise
for a 40M AM homebrew project. Thanks Ralph WA2NTK
