[Jukebox-list] AMi motors-was-My AMI F120 on Youtube

[Aaron's Email]

The board - which is basically a big piece of cast alluminum, certainly
amplifies the motor. I remember the first time I took one of those motors
apart and fired it up on my bench, I though that it as pretty quiet and that
I had done a successful job of restoring the motor to "factory." Man, was I
shocked when I put it back on the mech board! It sounded like it was trying
to unbolt itself, jump out of the jukebox, and chase me out of my shop!

distance from the phono. Perhaps the mech "board" amplifies the sound?

motors are "better" then the newer ones, and that there were several types
of those motors that appear the same, but will not interchange. Anyone know
for sure??
