P-channels are probably not necessary in their business plans.

Sony VFETs? Yes, I was absolutely considering doing that. Maybe putting my ZV9 and F5 on hold for a while.:spin: Ebay is a terrible place ...:cool:

Have you managed to get datasheets of VFETs?
The VFETs are similar to a JFET, except for power (?). But I think I remember something about burned VFET amps in abundance in the 70ties/80ties, or was that maybe the Sony class D with VFETs? (Rumoured to be a not so good implementation.)

I found a few shematics of DIY VFET amplifiers, not All-JFET, so maybe i is funnier to have Google translate them to English...
Anyway, found these:

Even Hiraga have used VFETs http://www.tcaas.btinternet.co.uk/hiraga2.htm
