CV63 triode

CV63 The valve measures 110x40mm overall

The prototype for this valve was E1323. See also CV344 which is a selected version of the CV63

Heater voltage 6.3V
Heater current 0.8A
Max anode voltage 2.5kV
Max anode dissipation 2.5W
Max anode current 500mA
Mutual conductance
(Vh=6.3V; Va=100V; Vg1=-3V)
Efficiency at: 225MHz 35%
260MHz 32%
290MHz 17%
300MHz 12%
Max frequency at which valve will oscillate 250MHz
Cag 3.65pF
Cge 4.9pF
Cae 1.35pF

The above ratings are with the valve used under pulse conditions and anode modulation. When grid modulation is used the anode voltage should not exceed 500V.
