The 16A5 was designed for low frequency power output either as a television frame output valve or for audio use.
This valve would normally be found in audio stages of television receivers. A pair used in push pull class AB1 would deliver 9 Watts at 4 % distortion. The peak to peak grid signal voltage would be 26 Volts and the shared anode load would be 4,000 Ohms.
The anode covers almost all of the internal structure. The control grid heat sinking fins are visible at the top. The wire grids can be glimpsed through the hole in the anode wall.
The thin glass tube envelope is 20 mm in diameter and, excluding the B9A base pins, is 70 mm tall.
