The QQV03-10 is a Mullard design and follows the European pattern of a central common core and two spaced anodes finned for greater heat sinking.
This valve type was much used for mobile VHF transmitters, as well as drivers for the larger power valves. such as the QQV06-40A.
In keeping with the Mullard practice the heater is centre tapped to enable operation from 12.6 volts as well as the normal 6.3V, thus making them directly suitable for operation from vehicle batteries.
See also CV2798 for detailed pictures of the electrodes.
The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins, is 70 mm tall.
