I'm looking at trying to upgrade an early model Jobo CPA2 with the upgraded motor that can handle the 3000 series expert drums.

So far I've found that you can use a BMW wiper motor or buy a new motor from Jobo. However, Jobo's tech bulletin mention's that there is a different circuit board to run the upgraded motor. Also there is a "new-style conical drive shaft, with a screw tap to lock in the main drive cog."

Has anyone done this motor/cog and circuit board upgrade?
