[sdiy] anybody used a Freeman string machine?

[Bob Weigel]

Hopefully somebody can save me trying to figure out the diagram of the 
bussing on this thing.  I've completely gone through it...rebuilt 
keyboard, repaired cracks in boards and bad solder and blown transistors 
and missing chips and bad capacitors and on and on.  12 hours or so 
later... all working great except I'm wondering if it's normal when you 
press 'low' out to be totally missing the upper octave.  -Bob
