He bought a lot of Sony VFETs but he did not have enough for commercial production. He then had a now defunct company SemiSouth make a batch of SITs (static induction transistor - also known as VFET or vertical field effect transistor) at a price of $300,000 which he uses in his First Watt SIT amps.

He designed a VFET push-pull amp and in collaboration with DIYAudio, made available his Sony VFETs in a diy kit for diyers (I have one). Apparently he has a single ended design that will also be made available in kit form to diyers soon too.
