Hi Brooke,
I have a 107A/BR manual, that is out on loan for a
few days. I'll make it available to you when it comes
back.
As to the 1KHz whine. It can be improved a lot by the
simple act of cleaning the gears, and replacing the lubrication
in the ball bearings. The motor gets louder the more heavily
it is loaded.
