[Jukebox-list] AMI PUSHBUTTON QUESTION

[Gary Young]

Wes, your description is bang on. I had exactly the
same problem with my AMI B when I first bought it many
years ago. some of the A sides, then all the B sides
went out. If I remember correctly I just soldered a
new jumper wire across the problem switches. Never had
any problems since. When I have a chance, I will look
and remind myself exactly what I did.
