Default parafeed plate choke calculation

After the relatively successful result of my 12b4 parafeed amplifier, I want a higher powered parafeed amp.

Am thinking of doing a 2a3 parafeed amp, using a 5670 for a driver.

I will have a custom wound plate choke. How do I determine the optimum plate choke inductance for the 2a3 in parafeed circuit?

Thanks.

There is an Excel-based calculator at:

Have not tried it for poweramps though.
