Karl,
  Those models operate just like a  'remote wallbox". They have a "pulse generator" and a "pulse converter".  The generator is what is found in a wallbox (or, in this case, the "selector" inside these model phono's. It "pulses" various times depending on the letter number combination selected. The "converter" is called a "stepper" by most other brands. It follows the pulses (or "steps-up") and "converts" it into a form that can then be used to "pull" the selected pin. Different companies used different "pulse trains" to achieve this, but they all used two "stepper gears" (or "wheels") and sliding contacts, of some type, to "matrix" the info.
  It sounds like the "alignment" may be slightly off, or one or more of the sliding contacts on the rear of the converter are bent/broken.
  Hope that clears it up--a little. Ron Rich

  Well, I wound up with this AMI Model H. I have gotten most things to work on it but I am having trouble with the selection system. It will Select the correct record for letters A & B and E & F but not C & D. I have the manual but I am having a hard time understanding the "Pulse" concept. It sounds like it allows the converter to rotate longer or shorter depending on the letter/number chosen??? I admit this is probably fairly elementary to those who know these older jukeboxes, but I don't. if I understood what is supposed to happen, I'd probably stand a better chance of figuring out why it isn't happening...hehehe. Any help would be appreciated.
