[Boatanchors] 500 watt butterfly

[Barrie Smith]

I'm in the process of gathering parts for a push-pull pair of tubes that 
will be running 350/400 watts input on 75M only.

I have a "kilowatt" butterfly capacitor that will work FB, except for the 
size.

I know that some of the early manufacturers built small-than-kilowatt 
butterfly caps, but I don't think I've ever seen one.

As close as I can come to describing what I'm looking for is "500 watt 
butterfly cap" ?

Since I don't seem to know exactly what I'm looking for, does anyone else?
