The PC88 is a UHF triode designed for grounded grid operation in the front end RF amplifier in Band IV and Band V television tuners. Mullard describe the PC88 as: a UHF frame-grid grounded grid amplifier triode. Miniwatt is a trade name of Philips and Mullard are the UK subsidiary of Philips.The construction is planar. The flattened cathode has a frame grid to one side only, beyond the grid is a square U channel anode with its flat end to the grid. The approach to a minimising the lead inductance is to use multiple pins for the grid connection. The relatively high anode current was employed to reduce noise.Mullard designed a UHF TV tuner around the PC88 operated as a grounded grid amplifier and a PC86 self oscillating mixer. These designs date from 1961.The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins, is 47 mm tall.References: Data-sheet & 1040. Type PC88 was first introduced in 1962.
