[Jukebox-list] AMi Pulse conv.

[Juke of Shrewsbury]

Ron, Your great memory serves you well! I have never restored a manual, but 
did a service job on one recently and your description is spot on. The 
mechanical gearing provides for a number wheel and a letter wheel. The 
customer turns the number wheel and the letter wheel automatically moves one 
step (one letter) every rotation of the number wheel. (or the other way 
round??) This set up makes the positioning of the wheel less critical, 
providing a 10:1 ratio between revolutions of the select wheel and 
revolutions of the pin pusher.

This was a neat arrangement and certainly more reliable than the pulse 
converter! ....but most people prefer the "traditional" push button 
selection system.

Adrian.
