The fact that you can get schematics for old stuff is simply great. Friend of mine was working on a SP-8 - turns out there were something like three or four pretty distinctly different versions of this product - because the unit had been worked on by others (a lot) - it wasn't completely clear what it was at this time in it's life. Tech sent out two schematics - units fixed and sounds absolutely wonderful.I would also agree that Leonard is a champ on the old stuff - product knowledge is so rare today.
