Caution re Origin Live motor upgrade kits
It just cost me well over $1,000.00 Canadian to fit one of these kits to my Thorens TD126II turntable because the advertising is misleading and instructions are minimal. Origin Live claim that the process was virtually identical to that for the Linn Sondek LP12 - as they had in the extensive corresponce I'd had with Mark Baker I'd had before before ordering - and sent only half a page of text and two diagrams relating to that turntable as actual instructions on physical installation (as part of a longer, 7 page leaflet). Because the motor has a completely different form factor (the Thorens motor+mounting are triangular and the OL is rectangular) new mounting points had to be fabricated. Because the resulting drive area of the shaft sits much lower and a substantial billet had to be machined. 3.5 hours of work for a couple technically astute people, one of them a very experienced audio technician plus machine-shop time.
