P-Series Valves, what to do with them?

[peter scott]

Perhaps Dave means constant current since all the P series run on 200mA. You could design a high voltage supply that was limited to 200mA if you wanted flexibility to run different series configurations of valves.

I'm sure that 200mA is a typo and that Peter knows that P series are 300mA.

Oops! Not a typo, just poor memory. I knew it was something like that.
