The PC86 is a purpose designed UHF oscillator triode for television reception. Mullard describe the PC86 as: a UHF frame-grid mixer/oscillator triode.At UHF a coaxial design would normally be used but by connecting the electrodes to several pins the manufacturers achieve the desired result without the complications, and cost, of a disc seal valve and its mountings.Mullard designed a UHF TV tuner around the PC88 operated as a grounded grid amplifier and a PC86 self oscillating mixer. Our other Mullard PC86 has a different internal construction. Neither were made in the UK. This example has yellow paint suggesting 1969-70 manufacture and the word to describe the overseas manufacture is the pejorative term 'foreign'. We have another PC86 with the later logo and on this valve the overseas manufacture is the bland, and more politically correct, 'imported'.The thin glass tube envelope is 20 mm in diameter and excluding the B9A base pins, is 47 mm long.References: Data-sheet & 1040. Type PC86 was first introduced in 1962. See also 1962 adverts. |
