CV273 UHF triode
CV273 UHF disc seal triode. This could operate up to 3.7GHz and replaced the larger CV90 in 1945 as a local oscillator.
*: At Va=250V, Ia=20mA. The anode seal temperature must not exceed 140C. The specification states that in order to achieve this and also limit the rate of change of anode seal temperature it is necessary that the mass of metal in close thermal contact with the anode disc is 2oz or more or brass or equivalent. |
