A device to convert 110V ac, 60 Hz to an appropriate ringer voltage at 20 Hz is in the current Fair Radio Sales catalog (Lima, Ohio). It costs $7.95. I'd give more details, but the catalog is at home. Chuck Bowden, WB7R, chuckb@tc.fluke.COM John Fluke Mfg. Co., Inc. M/S 232-E, P.O.Box C-9090, Everett, WA 98206
