frequency change jukebox 45 pcm (LPC1)

This precise gear set is for converting American 45 rpm Seeburg mechanisms for 50 Hz use, starting with the M100B model. It is also required for Library and Custom Unit models 200LU1-3, 200CU1-3, and Console Unit 200C1 and 2 (1952 through 1957). Will not fit models designed with the 45TASUx auto speed unit used in the LPC1, LPC480, APFEA1 and SS160 jukeboxes. You need some technical skill to change these gears. However, an illustrated instruction that comes with each gear set might help.
