Hi Mark, Just a quick "redeeming" note from my other post to you. I checked my web page and it wasn't my web page that identified a 60pF toroid at 1.8kva. I had recommended kva input to coil geometry (diameter/length of secondary), not toroid size. Whew, I feel a little better now. (I still think it's too much - experimentation will tell the tell). Good luck, Bart
