Korg DW8000, Mono/Poly, MS-20...

A wee bit more to it than that.
According to Korg service bulletin for poly-61.
1) remove R70(470 ohm)
2)Remove transistor Q10
3)Rep-lace nicad with lithium battery in same location
4)solder one 1N914 diode(or equiv) at location R70 and and another
between Emitter and collector of Q10( cathode to C and anode to E)
5) if the CPU board is KLM475, change R146 to 2.2k ohm.
if Cpu board KLM506 disregard R146
pretty sure this procedure is accurate from more than one experience.
the diode at position R70 by the way, mounts on the PCB with its anode
pointecd towards Q10, cathode pointed towards(not connected) the
positive end of battery.good luck. Russ
