Well, when I layed out the board (which I'm now stuck with) I *did*
keep the head and mic pre-amp section away from the motor.  Now I find
that the pre-amps don't care about the motor, but a line-level op-amp
buffer circuit and the headset power amp *do.*  Not very nice.

I shielded the pre-amps to stop FM radio reception.

Well, that's a good description of these motors, except the "band" is
around the transistor speed regulator board inside the motor-

So why is this wonderful shielding not working?  Maybe magic can only
be made by Sharp Corp.?  Do I need to turn Japanese?
