Thanks for that bulletin. Do you happen to have a parts page or exploded view of the motors/tachs that are being referred to? That would be very helpful to us neophytes!

Maybe Gus is right...my machine has quieted up a little more with some use. After tuning the drives in according to what George posted, they quieted down alot...the remaining hum has lessened considerably since then...sounds pretty good to me now.
