The SH-55 Seth Lover Model is a perfectly faithful recreation of the original 1955 design. The SH-55 utilizes the same nickel-sivler bottom plate, Butyrate plastic bobbins, plain enameled wire, Alnico II bar magnet, wooden spacer, black paper tape, braided single-conductor cable, and nickel plated nickel-silver cover as the original. The DC resistance of each SH-55 is recorded along with its serial number and maintained in Seymour's files.
