Default Screen current

Hi,

I want to use a KT88 in pentode connection, for a CCS stage (this).
The working parameters are:

CCS current: 100mA
Plate voltage: 300V (it will swing from 100V to 500V).

How can I calculate the screen current? I mean, I need to calculate the necessary power supply for the screen voltage; at the moment the PS is a separate one, too expensive.

Ciao,
Giovanni
