    martin - i watched your video and noticed that the coil assembly came off while you were desoldering the wires. I'm thinking that the 10W pump has more winds on each of the 6 coils compared to the newer DDC3.1's giving the DDC3.1 higher RPM output and amp draw.

    My question is, if anyone has tried re-winding the 10W pumps with lesser winds to bring it up to DDC3.1 specs and using the Toshiba pcb. If i had spare pumps to try out, i would do this. Count the number of winds/coil of the 18W version and wind the exact amount on the 10W version.
