RCA Radiotron


The RCA Radiotron manual has been prepared especially to supply technical information regarding the characteristics and operation of RCA Radiotrons to those who work or experiment with radio tubes and circuits.

Careful consideration has been given to the selection of material which presents general and specific tube information in the most useful and helpful form.

Tube types have been arranged in numerical sequence on the basis of the last two digits of model number designations. This is in accordance with our program of generally utilizing a two digit system for identifying tubes as evidenced by the new type numbers, i.e., 46, 56, 57, 58, and 82.

Eventually, the two digit system will be extended to practically all of the older-models by dropping the first digit of the present three digit designations.
