Vintage Synth Repair

The K2500R used the a K2000R power supply with a couple of updates, mainly some jumper under the board for incresed current flow and the 7812 regulator for digital was upgrade to a 78T12 that handles another half amp.  If you look at yours, you will see the silk screan says k2000R.

    I received the service manual.  I replied to let you know that I
    have received it but regretfully my email provider (dreamhost) seems
    to be blacklisted, so my response were rejected.  Here's hoping that
    yahoo isn't blocking me as well, and that this one will go through
    to the list!

    power/audio PCB/schematic from the K2500R that I have doesn't seem
    to be included - there are K2500/X and K2000 power boards in there,
    but no K2500R.  But I've had some progress regardless and will
    report more in a week or two after I return home from a trip and
    find some more time to work on it!
