Vacuum Tube Circuit Books

[McIntosh, Malcolm]

I came across three interesting books which deal with Vacuum Tube
circuit designs.

"Vacuum-Tube Circuits and Transistors", by: Lawrence Baker Arguimbau and
Richard Brooks Adler (1956)
"Reference Data for Radio Engineers", published by: Federal Telephone
and Radio Corporation (1944)
"Pulse Techniques", by: Sidney Moskowitz and Joseph Racker (1951)

They seem to have some oscillator and amplifier circuits :-) but not
much on filtering :-(
