The PCL82 triode pentode is typical of valve television receivers audio output stages.
The double valve enabled the demodulated audio signal to be amplified and applied to the speaker by using the minimum number of components and printed circuit board space.
The triode is seen on the left with the larger output section on the right.
See also PCL82 for a typical application circuit.
The thin glass tube envelope is 20 mm in diameter and excluding the B9A base pins it is 70 mm tall.
