[QUOTE="chipwelder, post: 56419, member: 54"] Am lazy at the moment... but Ja, I checked Norton website out after I posted... looks easy enough, except for the variac part, to optimize for the motors. Also I haven't been able to find a way to get the motor side pulley off the original motor, without damage, to fit the premotec, and I'm toying with fitting two or three premotecs to the AR... depending on whether they can be put far enough away frome tonearm or cartridge, am sure a motor underneath a cartridge or tone arm wiring is a bad idea...also load the empty spaces with something heavy and stiff... So, I can't see anything on the badgeless motor to indicate the speed at which it runs - so I have no idea what the ratios between the sub-platter and the motor pulley and the motor is at the moment... So am a bit scared to have TFx's built for this before I know what speeds it should run, I could probably see from the onboard psu what speed it's supposed to be doing... You know some of us peasants couldn't work out what a circuit actually does if the formula /schema smacked us in the face. Maybe I'm just dof and there is a constant in there that all informed people know about, and everything will be fine... (I guess 230V/50Hz and there are no transistors, so it has to be some known ratio between 50Hz and a ?xpole? motor?!?. but what? So for the moment I'm on easy projects, such as a chipamp with mp3player lod+headphonelevel + linelevel inputs and some cheap spikkas. [/QUOTE]
