The CV52 is a very unusual valve. The envelope folds over the pins like a hood, and the five in-line pins have a larger probe like pin offset to give correct orientation.

The valve has an anode dissipation of 10 Watts and was designed to operate at 50 cm or about 600 MHz. It is for use at this high frequency that the attempt has been made to minimise the distance from the electrodes to the external circuit.

See CV52 for detailed pictures.
