You can look at the schematics for the Intech COM-1000 amplifier
on my web site (www.n6rk.com). Although it is very conservatively
rated at 1 kW, I run it at 1.5 kW all the time.
I reverse engineered the COM-1000 filters and figured out that they
are simply 7 element Butterworth designs, right out of the handbook.
The capacitors in the filters are large transmitting types.
