The 30PL13 triode beam tetrode was designed specifically for service in a frame output stage of a television receiver. The requirements are low power and low frequency service. As with nearly all later television valves the heater is designed for 300 mA and operation as part of a chain across the mains supply.

The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins, is 70 mm tall.
