[Jukebox-list] AMI PUSHBUTTON QUESTION

[The Jukebox Junkyard]

   Steve, all your suggestions would work. But I use my mechanism timer that 
I developed for pre-tormat Seeburgs, adapted to the AMI circuits. The timer 
is reset upon making a selection and held in play position to prevent the 
timer from running out while the record is playing. I only did this because 
the bail switches were beyond repair.
    I also use this principal on the V/VL because the original scan control 
is so hard to work on. Wes
