AR13 / ZA/5712 triode
|This valve measures 115x55mm overall and has a BC4 base
This is a directly heated triode. The 1944 and 1946 CV Registers show this to be equivalent to CV1311.
However the 1963 CV Register shows CV1664 as equivalent, and the EVS datasheet
for CV1664 shows AR13 as
equivalent to it. CV1664 is clearly a later valve but the electrical characteristics are the same.
|Max anode voltage||190V|
|Anode impedance||5.5k ohms|
