Encore Phonograph Repeater

Interesting item manufactured by The Encore Co. Newark New Jersey. Definitely not something to be repeatedly used on now valuable machinery and records.
Additionally it is useable only on a few machines that will provide the clearances and other aspects fundamental for its correct operation. I also spent a fair amount of time fine tuning it but that may simply have been the fact that throughout its life it probably was handled and played with by numerous people.
