The CV136 is an output pentode valve for radio receiver use. In single ended configuration it will produce 1.4 Watts, enough for a receiver.

The CV specification demands full output at 100 MHz and so the intended use was not exclusively audio.

If used in push pull an output of 4 Watts is possible, but this valve was not expected to be used for hi-fi.

Copper supports for both inner grids and copper tape for connections to the base pins. The heater wire is an insulated coil.

The thin glass tube envelope is 17 mm in diameter and excluding the B7G base pins, is 46 mm tall.
