> Perhaps the connection from an inductive device is providing some sort of energy spike in the 6.3 v.a.c. transformer supply that isn't there in the other supply?< It could be, but my guess is that it's the difference between slowly ramping the DC supply up and holding it at somewhat less than the bulbs' rating and just banging them straight across a low-impedance AC source that accounts for the very different life. 73 John GW4FRX _______________________________________________ Amps mailing list Amps@contesting.com http://lists.contesting.com/mailman/listinfo/amps |
