The PL38 was designed for use as the line output stage of television receivers. Mullard also made the PL38M, and this differed from the standard valve in that it had an external metalising.

The peak anode voltage surge could be up to 8,000 Volts. The screen grid dissipation was 8 Watts.

The classic envelope is 42 mm in diameter and, excluding the IO base pins, is 118 mm tall.
