First off, this is a table that I have had for some time. I've owned 3 or 4 in the past, and this was the one I wanted to rebuild. The others turned into ARMod and ARCom if you recall.
The stuff on top of the plinth is actually EPDM foam. The one in front is a safety net for an accidental drop of the arm, and will catch the stylus before it hits the plinth. The one in the back is to catch the counterweight.
You might also notice the arm rest has been reinforced with an aluminum tube outer sleeve.
The tonearm is another story. If you have one that is not working the best, it needs to be taken completely apart and cleaned, especially the big brass cylinder and the outer sleeve it fits into. These two parts must glide with in each other. Then put all that back together. The stem that fits in the well should be heavily coated with 1000cs liquid silicone. This takes out any wobble from the stem into the tonearm well, and is the source for the anti-skate effect. The liquid silicone's molasses effect works wonders to damp the whole thing, too. Next, the set screws must be tightened so there is no slop between the arm assembly and the inner brass cylinder.
The innards of the table have had select spots treated with good old plasticlay. The wiring system has been redone with modern techniques. The motor is the Haydon motor, but is a replacement that I found on ickbay. The thrust washer was simply turned upside down to the unworn side. The platter shaft was lubed with Slick 50.
The turntable mat has been replaced with some tape gasket (1/8" thick by 1/4" wide) placed around the perimeter of the outer ring. That is the only place where the record makes contact with the platter.
It's not done yet, as it needs some decent feet and some other odds and ends, but It's almost there.
Certainly one of the most interesting tables of it's day, it kind of is a pain in the ass to work on, because of the tethered tonearm, and its design appears simple, but its actually a design from some very deep thinking. I think they sold for some $6X dollars back in the hey day. My first table was an AR (the Empire replaced it).
