I will send you the service manual direct - my unit is a K2500R (rack) 
but I think the K2500 (keyboard) schematics and board layouts were all 
present and correct.  I've determined that my unit actually works OK 
after an hour or so of warming up (even though I live in a relatively 
warm area), which firmly points to bad capacitors.  But a recap is on 
the back-burner for me at the moment, too much other stuff on my plate 
:-(  Lots of boards to remove to get to the power supply board at the 
bottom of the rack!


Cheers,
