Been seeing where someone posted wondering about Jim Karbowski's notes on all his coil designs. Being a Bigfoot coil fan for years and seeing posts on it was a simple technology, i contacted the guy selling his estate on feebay and bought them a while back. And no they weren't cheap! After looking through them, i can tell you Jim Karbowski was a genious. And the guys who think they have it figured out haven't got a clue!
Also a mystery was the email exchanges in the back between Bill Lahr and Jimmy Sierra trying to reverse engineer the coils. Just guessing after Jim died his wife let them borrow the notes, since Bill is now likely the guy who you would send a bigfoot coil to, to get it fixed?
Just had to have these notes so i knew where they went. Not sure if i am going to sell these down the road, or donate them to a detectorist type museum after Jimmy Sierra leaves us?
