The PCC89 is a high gain, high frequency, frame grid double triode for domestic television receivers. It was designed as a cascode RF amplifier to operate in Band III up to 220 MHz.
The packaging used by Mullard for these relatively modern valves featured a moulded plastic carrier within the card box rather than a corrugated wrap.
The thin glass tube envelope is 19 mm in diameter and, excluding the B9A base pins, is 57 mm tall.
