I’ve had my main table and air bearing arm in place since around 2006-7, various cartridges over the years. With the big Minus K below it, the thing is substantial in weight and size:
Several years ago, I had Bill Thalmann restore an SP-10 (mk I-- not so common, nor as desirable as the later iterations) but I've owned it since 1973, when it was new. He did a Krebs mod and replinthed it. Other than changing the factory mat for something different, it was pretty straightforward to set up and operate:
I still prefer the big Kuzma. But it is a pain to isolate (unless you are on a slab) and if you use the air-bearing arm, you’ve got the complications of an air compressor. The arm works magic with the stone-bodied Koetsus.
That old Technics is pretty bulletproof. I used it from 1973 until the mid-80s, when it got parked until it got restored in 2017. It’s a nice table for the minimal investment I have in it, and plays in an entirely vintage system elsewhere in my house.
