I have a Mint Protractor that I used for many years prior to purchasing the SmarTractor I currently employ. Using the Mint, compared to my previous alignment gages, revealed I was close in my setup but the last bit of precision provided an audible improvement to my ears. Yip makes each one custom to an individual turntable/tonearm combination. Mine were for Origin Live table and tonearm. He will require some input including the diameter of the spindle so it is a tight fit. He included a magnification glass at 3x and offered an additional loop at 10x. Opt for the additional purchase of the 10x. Yip was very attentive and communicative so I would assume, if he is still in business, things are a little difficult in Hong Kong. Worth pursuing unless you want something to work on multiple tables then look at the SmarTractor. Send a PM and I can give you some addition insight on both those options.
