Try any handbook before 1957 when transistors became available.  If you can't 
find them at the ARRL, try E-BAY as they are only available used.K5EWJ

Fascinating discussion. Anybody know of any noteworthy books that cover the 
subject? Especially tube transmitters and their antennas. Given my love for 
Steam trains, breadboard receivers  and Ham Radio, I sometimes think I was born 
about 50 years too late!
