There's an excel program named: 1.xls

do a seach for it (diyaudio search button) then download and learn plenty of good stuff about the AX.

Good luck,

John

Hi,

it will allways be class A. No AB possible!

30V is quite a lot for this bridged amp. I would go lower.

You could use the 220vac primaries rather than the 115vac primaries for the 115vac supply in the US.

Just an idea.
