Adam,
Now this is probably the most important bit of news in this whole thread. This is really exciting and I can't wait to see what you find out. I have wondered about the real voltage limits of this design. Paul mentioned 144 volts for sure, maybe 156. Now you are going to show us the real limit.
Good luck with this testing. I'm sure I don't have to remind you to post results. Take your time and get as much data as possible.
And thanks again for the pretty pictures.
Eric
