Hi Arturo,
The Kiwi power supply board is optional, I think, and not necessary for the Kiwisix upgrade.
However: I too have had a lot of P6 and Mono/Poly synths in for service where there are suspicsualy lots of the 40xx chips that have failed, and not only because of the battery problem. So there might be some in Kiwitechnics statement that the poor power supply board is at fault. But then: so it is with many old synths. Most old synths benefit from power supply upgrades, like swapping out old electrolytics, power regulators and even diodes in the power supply regulator board.

Hi Terje,Do you also recommend the Kiwi PSU upgrade when replacing the KLM-367? They seem to suggest (from what I remember) that the the Polysix PSU design is flawed and is the cause of the battery issue. Would replacing it be necessary if one is replacing the KLM-367?Thanks,Arturo.....
Sent from a Roland TR-808.This is my dream repair and mod job! Very impressive, Terje.
Thanks!My feedback after repairing lots of Polysix´es, and cleaning up many processor boards with battery leakage problems, many of them with similar problems like yours, all I can say is this:Get yourself a Kiwisix processor upgrade. It really is worth it. Very easy to install, and all your problems is history.
