According to VPI's price sheet info on their website "THE JMW-10.5i TONEARM HAS BEEN RENAMED THE CLASSIC 3 TONEARM". The 10.5i is included on the Classic 2 and Classic 3 tables, I believe. The Classic 1 has it's own arm (called "The Classic Tonearm"). It lacks the VTA tower of the 10.5i. Whether or not the 10.5i and the Classic tonearm have the same specs is something I can't answer.
VPI Classic original vs newer tonearms
I recently got the original (square corner) version of the VPI Classic 1 turntable. I understand the newer rounded corner model has a few changes that they have made--a new platter, an aluminum heatsink for the motor, and a slightly longer (6 mm) tonearm. I am working on ordering the Mint LP tractor from Yip, and he is not clear on the model tonearm I have. The best I can tell is that I have the JMW Memorial 10.5i SE. Is this correct? Isn't the latest tonearm called the Classic SE Tonearm now? I would call VPI but they are closed til May 3. Thanks to you Classic owners who can help!
