Hello,  Here is the tracker bar diagram for the Violano.  It is
from an original copy of the 'Violano Service Manual'.

Please forgive me if this sounds a bit offensive but I feel that
I should add a warning to my message.  From your question I suspect
that you know very little about the Violano.  Most collectors and
all restorers would know where to find a diagram of the tracker bar
or the wiring for a Violano, so it appears that you are a new owner
or you are trying to restore a Violano for the first time.

That said, I would like to warn you that a Violano is not the type
of instrument that you should mess with casually.  It is quite easy to
damage various components or set fire to something.  In fact, it might
be possible to set the whole machine on fire if you were really unlucky.
The relatively high current, a large capacity DC power source and a few
dozen large inductors also make it possible for you to kill yourself
quite easily.

If you don't know what you're doing, I'd suggest that you contact a few
people who do and ask lots of questions _before_ you touch anything.

You might also consider joining one of the organizations (like MBSI or
AMICA) that specializes in mechanical music.  You'll meet lots in
wonderful, interesting people who are most helpful if you ask nicely.
In fact, one of the members (also a MMD subscriber) wrote the book on
the Violano and another member makes a full time business of restoring
them.

Regards from upstate New York,
Craig Smith

P.S.: I restored my Violano many years ago.  I finished it the week
_before_ Harvey Roehl published the Violano book.  Boy, I sure miss
Harvey and Marion.

 [ Thanks, Craig, I'll place the diagram at a new web page for Mills
