Original poster: "by way of Terry Fritz <twftesla-at-qwest-dot-net>" <dhmccauley-at-spacecatlighting-dot-com> I want to remove half of the shunts from my open-frame 4kv/20mA transformer but have been unsuccessful. How do I remove these shunts. Do I really need a sledgehammer to do so??? Seems those suckers are epoxied or something in there. Any help appreciated! Dan
