CV35 WWII reflex klystron, a frequency variant of the CV36 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 CV35 itself was an improved version of the original NR89 "Sutton Tube"
