Townshend uses an AC motor for the Rock 7. Maybe contact them about it and their opinions.

I think you had better do some research - I used to import Rocks and they all had AC synchronous motors, to which you could add the Merlin power supply.
The original arm would get sticky bearings, they are loose inside and there is a fix, but I'm not sure if I have the instructions any more. The sound improved significantly with the Merlin speed sontroller - more open, smoother, bigger soundstage. You might be better off putting the money into a speed controller.
The Rega arms were a popular combination with the TT. There was a paddle available to bolt onto other arms.
That's very helpful. Out of interest were the townshend motors low, or high torque? I am begining to prefer the swagger and stride of high torque decks that seem to have little or no problem with time smear during complex passages. This is as opposed to 10 years ago when I was obsessed with image and inner detail (grass is greener on the other side I guess).
locating the Merlin power ssupply is a bit like finding hens teeth - I am told that the new merlin works on the elite rock, but anything north of 1000 is a lot of money.
