The PCL84 is a television triode and output pentode. Granada were one of the main ITV companies in the UK and also one of the major TV rental businesses, they did not make valves. It is interesting to speculate as to who made them.Within the envelope the triode section is quite small, about 2.5 mm thick and the anode cavity area is 18mm x 7 mm. The output pentode is 11 mm front to back with a similar anode box area. No audio power rating has been found, this suggests a use in video output, but Mullard are not specific as to use, other data sources confirm the video function..The thin glass tube envelope is 20 mm in diameter and excluding the B9A base pins it is 59 mm tall.References: Data-sheet & 1040 |
