The Sperry 2K41 is a two-cavity mechanically tuned klystron used in various military radar and communications systems. This tube generates frequencies from 2660 to 3310MHz, with a filament voltage of 6V, beam voltage of 1200V, and a reflector voltage of 750V.

2K41 Datasheet

The Sperry 2K41 has two resonant cavities which are separated by two sheet metal diaphragms. A complex system of levers and springs allows the length of the tube to be changed by flexing the metal diaphragms.

2K41 klystron. The nestled knobs on the side of the tube perform coarse and fine tuning adjustment.
