Hey folks. I have a Mitchell Focus One turntable with SME series 3 arm. I have heard that there was an 'S' model which had some motor improvements but I am not sure which mine is. I have recently done some tweaks to improve the motor by adding some nylon washers which made a big difference. Does anybody know what the original mod's were or if anybody is familiar enough with this TT, how to improve it more. Thanks in Advance, Snoo.
