The ARP12 penthode is not an equivalent of VP22!.

The VP22 uses 100 mA heater-current and has a different performance.

The VP23 is equivalent to the ARP12 and consumes 50 mA heater-current.

Hello Jan

I have entered these data. I hope they are all correct, since some Brans Tube Vademecum - editions containing many errors.
