NR82

Sensibly equivalent to:
CV1193 VR99 W1532 X65
    
Extras ▼

 

The NR82 is a triode hexode, and the NR denotes that it was designated for use with the UK Navy as a receiving device. The direct commercial equivalent is the X65 and when the CV register was built the NR82 became the CV1193. The envelope also carries a second Type designation - W1532.
The triode was designed for local oscillator use and an injection voltage of 10 V peak to peak was produced. The hexode mixer took the signal into the top cap grid, thus maintaining the greatest separation between grid and anode circuits.
The reverse is plain. The dark coating is internal.
The classic envelope is 38 mm in diameter and, excluding the IO base pins, is 97 mm tall.
