The PCL83 is a television audio triode output pentode with a main role as frame oscillator and output stage.
Marconiphone is a brand name used by M-OV.
This standard design was made by several manufacturers. We also have other examples: PCL83 from Brimar & PCL83 from Mullard.
In the envelope the two electrode systems are side by side. The triode being much smaller anode. The wire grids can be seen through the hole in the pentode anode.
The thin glass tube envelope is 20 mm in diameter and excluding the B9A base pins, is 47 mm tall.
