Radio Valves

Hivac PX230

Directly heated output triode

Hivac PX230

The only data I have comes from the AVO Valve Data Manual, 15th. 1962 edition. The filament voltage is 2.0V. At Va=150 Vg1= -15, anode current is 17.5 mA and gm is 3.5 ma/V (mS). Anode dissipation would be about 2.5W under these conditions. Hivac specialised in miniature hearing aid valves. Conventional full sized valves are unusual. This one has a late type B4 base with spiral cut pins. The box for this valve has great graphics
