The 2K33 is a disc-seal klystron, the waveguide size suggests an operating frequency of 22 - 25 GHz. The tuning of the cavity is by integral knob fitted to a fine thread screw in much the same way as a micrometer and this adjusts the cavity length. There is both a scale to denote the position around the circumference and a linear scale showing the number of turns. Output is 40 mW.
The wide metal tube envelope is 30 mm in diameter with the active glass envelope within, and excluding the IO base pins, is 110 mm tall.
