Hi,¶
On the back of the changer mechanism there is a small, cylindrical piece that
transfers control from the disk raising mechanism to the playing mechanism.  I
suspect that it is sticking sometimes, thus allowing the changer to continue to
cycle and exchange for the next disk.  If you want to check this, AND YOU
SHOULD BE  V E R Y C A R E F U L,  open the back of the machine and look at the
area between and behind the two springmotors.  This little part (about 2-3
inches long) will toggle/slide up and down along a bar as the machine goes from
change to play and back.  It could also be that the latch is missing once in a
while.¶
Now, Denny, I'd be VERY careful about trying to fix this yourself if you
haven't done any music box restoration before.  If you move the wrong lever or
loosen the wrong screw it could easily grind up some of the gear$.  It is also
VERY possible that it will eat off a couple of your fingers and make some
extremely loud noises in the process.  Those springs and the attached mechanism
can be VERY DANGEROUS.  I almost lost a couple of toes when this machine
dropped a disk from the play position unexpectedly and it cut 1/2 ich into the
bottom of the case.¶
If you message me back, I will be happy to put you in touch with someone near
you who can help if you feel you need it or do the job for you.¶
Regards,¶
