Yamaha CP-25 schematics

2004-01-25 by Brian Andrew Marek

Does anybody have schematics for the Yamaha CP-25 electronic piano?
Only the user's manual exists on the web (as far as I can tell).
Something's wrong with the preamp circuit (extremely weak output) and
without the schematics I seem to be groping in the dark...
