Crumar Musical Instruments User Group.

I play the Crumar Organizer since 1974. 
As it was one of the first demo parts at the beggining 
of its production in Italian store, I haven't got any 
printed material (Users Gide, Technical Manuals, 
not even Warranty). It is not the T1, it had been made 
some years earlier (Take a look at Photos!).
I need Schematic Diagram as the Vibrato unit "died"!

Could You help me?
