CV2380 low-power magnetron
|
This valve measures 51x17mm
overall and has a B7G base. |
This is a low power pulse type
magnetron using spatial harmonic operation. It carries the serial number
201, and internally the numbers 362 and A5022.

Max pedestal voltage * |
400V |
* Under pulse conditions, the
maximum pedestal voltage is the maximum permitted DC component of the
total applied anode voltage. The current from the pedestal voltage source
shall be limited to 5mA. The use of a pedestal voltage simplifies the
modulator design so that a simple blocking oscillator can be used.

The magnetron in its holder,
which consists of a B7G socket and a bakelite housing. This holds
the valve into the waveguide assembly. |

Above is the waveguide assembly
with the valve installed in the right hand side. Below is a closeup of
the rear showing a small hole. This area is presumably where the necessary
magnet would be positioned.
