For reference, use the schematic here: http://www.passlabs.com/pdf/cascode.pdf page 4, figure 9. Assume a +/- 75V on the main rails, this will give 400W at 4R with a very lightly regulated supply.Assume a +/- 37V supply fed through a pair of fast diodes to the emitters of Q9 and Q10.Thats it.You're done.400W with only four output devices.
