i just picked up this organ.  haven't even cleaned the dust off yet. 
it's in amazingly good shape for its age.  two of the three metal name
plaques still have the factory plastic film on them.  everything
works, but i think i need to open it up and clean things up a bit. 
the expression pedal quit working an hour afer firing it up, but i was
told it was an easy fix(burned out bulb).  the guy threw in a univox
pro verb, which adds nicely to the sound.  i've primarily played
guitar for the last 20 years, so i consider myself a hack on the keys.
 still, though, it's fun to play, and apparently not very common. 
anyone have any pithy advice or humourous antecdotes about this
particular beast?
