CV36 WWII reflex klystron, a frequency variant of the CV35 and CV67. Operating at 1400V, these gave 300mW output with a reflector voltage of between -230 and -320V. They had a tuning range of about 5%, with two tuning plungers to pre-set the range and a third to adjust it over about 2%.

They were replaced by the CV116/CV237/CV238 and CV272 series.

The CV36 is an improved version of the CV10 - based on the original NR89 "Sutton Tube"
