The CV35 is a tunable reflex klystron that has an International Octal base and was designed to operate as an oscillator at a wavelength of 10 cm (3 GHz) and replaced the NR89.
A range of Types existed to this design, varying only in frequency. These were the CV35, CV36 and CV69. These all operated with voltages above 1 kV and were a problem for airborne use. The replacement design was the CV116, CV238 and CV272.
The valve is made with copper discs extending outside the glass with copper/glass seals. The resonant cavity is then bolted onto the discs. The body looks to be brass with the tuning adjustment as a bright cylinder on the right.
One port is open and the glass can be seen within.
The CV35 is stamped into the external cavity. The copper discs are clamped to the cavity body with the annular ring.
The wide glass tube envelope is 29 mm in diameter and, excluding the IO base pins, is 157 mm tall.
Reference: Data-sheet. Type CV35 was first introduced in 1941.
