Default Re: CV1326 = AC4/Pen ???

I have just measured the heater current of the old valves, one comes out at 1.90 Amps and the other at 1.85 Amps. So it looks like they too have a nominal heater current of 1.9 Amps, which is interesting as they are commercial Mazda AC4/PENs and not CV types.

They were measured under the same conditions as the CV1326s in post 10.
