[HAM] K100 schematic

[Hugh]

This is a long shot, but does anybody have a schematic for the power 
amp of a K100? It's a 1965 non-TG but tube amplified beast whose 
power amp I'm going to attempt to use as an amp/overdrive stage based 
on Kon's overdrive circuit in the Hammond Wiki driven by a T500 
single manual chop.  Any tips on getting the 12AX7 to go into 
overdrive on this amp also gratefully accepted.

Thanks,
Hugh
