Wes,
Thanks for the additional info. I tried to avoid this jukebox because I knew 
it was out of my area of expertise (I use that term loosely). Neither the 
customer nor I could find anyone in the Mobile area to handle it and the 
customer is a friend of a friend so my "honing" will begin on this jukebox. 
There is another one just like it, although a 200 select, sitting right next 
to it. Same customer owns both. Let the learning commence....LOL.
