Maybe not quite appropriate for this news-group..

Does anybody know a pointer to a program or the methods
of calculations so I can determine the losses occuring
in a PI-filter output for a high-power tube amplifiers.

I can calculate the required C1, L and C2 values given a
certain anode voltage and current and a certain output
impedance for a loaded Q of 10, 12 or other values, but
what about losses depending on selected loaded-Q values
related to harmonics suppression...

Thanks in advance,
Arie.
