Lespier,
Many people have done DIY with the EDS motors. From a service standpoint, capacitors C5, C6, C7, C8, and C9 can be replaced. You can basically use 4 sheets of 3/4" birch plywood, make a 5" hole, mount the motor, measure your spindle to arm distance, put it together, and perform a full setup. The shape of the plinth is your immagination. Maybe a modern tear-drop shape? If you want it to be beautiful, when you're done, add 3/4" mahogany to the top, round the edges, and use marine varnish to seal it. Wet sand between coats. Your choice if you want glossy or satin finish. For an armboard, use a standard Canadian hockey puck. The properties and composition of it make for an excellent isolator. If you want to get it more beautiful, finish the sides in flamed maple veneer. I regret to say I'm not familiar with the Revox TT's, but know much more about their reel to reels.
Sorry for off topic, Regards
