This valve measures 42x9mm overall, plus the 4 leads.

 

This valve is based on the CV495.

Filament voltage 1.25V
Filament current 13mA
Max anode voltage 25V
Max anode current 250µA
Mutual conductance 80µA/V
Amplification factor 2.2
Max negative grid current 1.0x10-12A

Above figures measured at Va=9V, Ia=100µA

Viewed from the base, a red dot indicates the anode lead, filament -ve is to the left and filament +ve to the right. The grid wire is in the centre.		 CV2269
