The Jig is up.
Thank you, Michael, for informing the public and I about your difficulties with the Tri-Planar pivot-to-turntable spindle measurement.
I extend my apologies to any Tri-Planar customers who may have encountered similar set-up issues. If your turntable spindle-to-tonearm pivot is more than 233.5 mm then loosen - but do not remove - the three mounting screws at the base of the tonearm and move the tonearm slightly toward the turntable spindle or rotate the Tri-Planar tonearm clockwise to achieve 233.5mm. If the turntable spindle-to-tonearm pivot is less than 233.5 mm, move the tonearm away from the turntable spindle.
When setting up the cartridge, the arm may need to be moved slightly. This is why #10-24 screws are recommended for the 0.250” mounting holes on the tonearm base, allowing for 0.065” of free space to move in all directions.
Based on your feedback, I will develop additional tools along with the drilling template to assist with achieving the exact 233.5mm dimension. In addition, I will update the instruction manual with pictures so setting up the turntable, tonearm and cartridge will be correct and consistent.
If you have any difficulty, please give me a call at 612-623-0922 or Email: tri@triplanar.com. I am available 9:00 AM to 6:00 PM, Monday to Friday and most weekends too. We are here to serve you!
Thank you for supporting Tri-Planar. Wishing you well and enjoying music.
