Article-I.D.: stolaf.891 Posted: Thu Apr 21 21:05:30 1983 Received: Tue May 10 17:30:22 1983 References: vax1.302 vax1.303 Using AC for a jacobs ladder works just fine. I have had one for several years, all it is is a 12,000 volt luminous transformer and a couple of wires. No problem with it it "going to zero volts", after all, ac only passes through 0 volts and does not go to 0 volts. The arc goes up to 3 or 4 inches (only 2 on a breezy day). -Paul R Borman -St. Olaf College ihnp4!stolaf!bormanp
