Fisher seems to have found the cure for the EMI complaint so a newer or new would be the ticket. I always though a lot of the problem was people ran it too hot because they didn't get it that it was designed to have a higher capacity than it was made to run at. Most machines seemed to have nearly a governor to make sure you didn't run too hot. Anyway, glad to hear you are swinging a detector again, Brian!
