If you search the web under "Maplenoll" you will find some people who are modding and tweaking these TT's.
As with any air bearing TT/arm, having it perfectly level is of paramount importance. Also there are issues about moisture in the air lines. It has always been known as a great sounding TT, if, you can keep it working. Enid Lumley did alot of experimenting and improving of the Maplenoll, and her info is around on the web. There was some changes to the air plenum under the platter, and 6 orifices drilled, instead of 3, for better platter stability. Heavier platters were also used. The main thing with a standard Maplenoll, is to get the correct dividing of the air pressure between the arm and the platter.Many have alot of trouble with this, and I don't know how to do it, because I've never owned a Maplenoll. But I have heard alot of stories about what a pain in the ass they are.
