The VX3192 is a Brimar (STC) development Type. It became the CV4062.

The VX3192 pentode is an audio power valve. In class AB1 a pair of valves in push pull will deliver 13.3 Watts. The input needs 30 Volts peak to peak and the anode load has to 7500 Ohms.

Also the CV data-sheet specifically mentions suitability as a series pass valve in stabilised power supplies.

In Class A, triode connected, the valve will generate 2.6 W at 1.4% distortion.

When fitted with flying leads for direct soldering into a circuit the Type designation becomes CV4065.

At the top all three wire grids can be seen.

The thin glass tube envelope is 18 mm in diameter and, excluding the B7G base pins, is 61 mm tall.
