The PL802 is a purpose designed video output pentode for driving a cathode ray tube with the wide bandwidth signal needed for colour TV picture information.The anode is shaped as a pair of flat plates either side of the grids with thin straps joining them together at top and bottom. the maximum anode dissipation is six Watts. The figures given are typical operating conditions but the maximum anode voltage is 300 Volts long term average with 400 Volts peak.
The construction is as a beam tetrode. The beam plates and the screen grid can be seen. The screen grid passed flat across the cathode.The thin glass envelope is 20 mm in diameter and, excluding the B9A base pins, is 59 mm tall.Reference: Data-sheet. Type PL802 was first introduced in 1966. See also 1966 adverts. |
