The QV04-7 is a single beam tetrode for transmitter use up to the low VHF region.
The design is all glass as were all of the B9G based valves. The valve would have been used for driver and frequency multiplier stages as well as for low power transmitters. It was designed for class C service.
The wide glass tube envelope is 31 mm in diameter and, excluding the B9G base pins, is 59 mm tall.
