Hello everyone,  My dad purchased a restored 146B Wurlitzer back in
1996 and the tracker bar was made out of clear Plexiglas.  The only
problem I had with it (since I inherited the organ) was that one of
the brass flange ears on the side of the bar that holds it to the
mount had cracked and started to bend.

I soldered it back in place and never had any trouble since.  By the
way, when they crack the organ starts to cipher and kick into rewind.

Yours musically,
Gordy Forcier
