This is an update on my Prime, which is sounding pretty OK now. My arm pivot to spindle distance was too long by 3.5 mm. A new protractor made to the actual distance solved that problem. The speed was off (33.5-33.6 rpm) and no amount of fiddling fixed it. An Eagle and Roadrunner from Phoenix Engineering has that issue solved. Note, my reference turntable is a KAB-SL1200 Technics, which the Roadrunner confirmed runs pretty much right on target (33.334 plus of minus 0.002 rpm), so the slightly off speed was noticeable in comparison. It is doubtful that this would have been a problem without the frame of reference. A periphery ring, HRX spindle and double belts were added more recently. All in all it has been a fairly long quest to dial the Prime in and if I had known up front what was in store I might have balked, but then every turntable requires setup attention. The end result is what counts and as I say, this Prime sounds quite good now.
