Extras ▼

 

The CV1501 is a small low power VHF transmitting beam tetrode used in WWII. In the late 1940s this type of valve was used as the audio output valve in simple radio receivers.
The end of the anode.
The anode is blackened for improved dissipation by radiation and oval in shape. The cathode and grids are flattened. Surrounding the grids and spaced away from the anode is a bright metal box cage with open sides. This is the beam forming plate assembly.
A closer view of the electrodes.
The classic envelope is 32 mm in diameter and, excluding the IO base pins, is 87 mm tall.
