The 16A8 is an equivalent of the PCL82 triode pentode and is typical of valve television 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 chassis would have been a vertical printed circuit board with the gun of the picture tube passing through it. Each of the tall valves would have been retained in their holders by a spring clip.For such receivers the valve technology had developed to the point that the valves would normally last the life of the set without needing to be replaced.
The small triode is on the right with the pentode section grid axis placed at 90 degrees to the triode. The pentode control grid is fitted with small heat radiating fins.The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins it is 71 mm tall.References: Data-sheet & 1040. Type 16A8 was first introduced in 1955. See also 1955 adverts. |
