The A B C of Vacuum Tubes, in Radio Reception: An Elementary and Practical Book on the Theory and Operation of Vacuum Tubes, As Detectors and Amplifiers

Slightly dated emphasis on radio, but if you want, as I did, a primer on vacuum tubes, this is the one.

Real nice book explaining vacuum tubes. Speaks well to the non initiate

great book.

Less technical than I hoped, but still some interesting perspectives.

Interesting to read what they thought of radio back in 1922. Good, non-technical, description of the operation of vacuum tubes and "variometers". Variometer are the rotating inductors that were common in radios of the 1920's.

Most excellent and quite educational.

Interesting book

GOOD REFERENCE BOOK

Excellent thank you quick service

Totally useless book ,number of circuits are less,only 4 or 5 circuits.. they are not clear and systematic..keeping below standards .do not purchase it, otherwise you lost your money
