Axel, That has to be one of the kewlest TT's I've seen. Removal of the arm was extremely easy, three screws held it down to the plith, unsoldered the wires, and disconnected the return mechanism via a hex screw. Then just lift it off, which left a very strange shaped hole. It was weird because the hole didn't seem to correspond to the arm whatsoever, except the tonearm shaft and the arm lift and anti-skate, which is to the right of the arm. I had to grind a small amount next to where the anti-skate was and using the SME plate as the template, ground it so I'd get full adjustment. Since the plith is made of a resin, it left quite of bit of very fine dust, since I used my dremel tool with a wood sanding attachment. The entire amount of material removed was probably less than the size of a bottle top.
