Most of this has gone over my head. I can confirm is that the back of the amp says it will handle 120 to 240 VAC. Sadly I have no world tours planned at the moment.
FWIW the F schematic should be fine. I have the G revision, but it only differs from F by the addition of one cap.
Other than that I understand "nur Bahnhoff" as the Germans say ;-) I had no idea how much EE talent there was on this board!
