Hi Frank, Any experience in Manhattan has to be classified as extraordinary. You might have been zapping pairs that were put in by John Carty in 1906. By the way, there used to be a theory that one needed to "zap" a line with high voltage first and then apply sealing current at low voltage and about 10 to 15 mA. This was later proved to be superstition. Only the sealing current really did anything. Bell Cos., as an aside, used to use breakdown test sets to force short circuits on paper and pulp insulated pairs with resistive leakage between ring and tip. This was standard Bell System practice based on the notion that a solid short circuit could be located more precisely than a high resistance fault with the Wheatstone Bridge instruments of the day. NY Tel had their own twist. They used to put two breakdown sets in series, a total of 1200 Vdc! When they found out about the practice, the safety people at AT&T went nuts. Another of the millions of stories in the Naked City. What are you doing now? George
