Keys and Tabs
 
The next step on the vibrato project was to check the switches.  I also had a short in the Second Harmonic percussion switch, so this was a good time to fix that, also.

I took the top off the organ and some of the metal pieces from the front.  This gave me access to all of the tab switches (left).  The vibrato switch was not the problem, but I fixed the second percussion.  I took the whole drawbar assembly apart for cleaning (bottom center).

While I was at it, I took all of the keys off of the upper manual and cleaned under them, as well as cleaning the keys themselves.

Luckily, I got everything back together, but I still have the vibrato problem. Hammond M-102 Friday, January 27, 2006
