Having the Linn style pulley (probably where the idea came from?) enables easy fine running speed adjustment. Use a non-mains high frequency strobe (avaiable on ebay I think) like the 300Hz Linn one..

At the time, the TT2 sounded slightly different to the Lp12, and of course, anything that sounded different to the LP12 was automatically worse I reckon that these days, the TT2 with modern takes on mat and tonearm, may well be a lot better if truth be told, especially the later model with the outboard motor supply, which I don't remember for some reason (probably because their speakers were being changed at around the same time and we weren't as keen on the new models (probably wrongly, but big Linn/Naim dealers were very narrow minded back then).
