Actually, I've never had to deal with Wilson Consulting. I worked entirely through Randy. But that's probably because its been a year since I started on the things and I still haven't finished them (mainly for lack of the output inductors and a autotransformer to bring the voltage up slowly for the first test).Its a shame to read that Randy has pawned off his tech support to someone else. I know he licensed the rights to the design to Zus, but hadn't heard about Wilson.
