[sdiy] Anyone have schematics for a Kimball Organ rhythm machine?

[aankrom]

I have a  Kimball Organ rhythm unit from a 600/700 series (late 60's 
early 70's vintage). The organ it came from had a service manual for all 
circuits, but the rhythm machine. The organ used weird, unmarked Ge 
transistors mixed in with some Si units. The rhythm generator is mostly 
2SB175's. Lots of bobbin inductors. I like the unit as-is, but I'd like 
to know what's what. I'm curious about the circuits making the 
percussion sounds. I'd also like to be able to trigger each sound 
externally and perhaps modify the preset rhythms (the ones I don't like. 
I'm making a box to hold the power supply, Ge power amp and reverb unit 
and the rhythm unit all in one box. The organ speaker is going into a 
large speaker box from an old RCA console stereo.
