Ariston has a very interesting history with Linn, which I will not get into. The basic design of the Ariston RD-11S is basically the same as an early Linn without the patent spindle bearing. It uses a more convention but, larger ball bearing or captive ball bearing. So, refurbishing this unit was fairly easy as I could source Linn LP-12 springs and grommets.
Some tweaks: Other than buying Linn LP-12 springs and rubber grommets. Replace the suspension screws with new 10-32 x 2.25" screws, wing nuts and washer. Keep the internal tooth washer to aid with retention. Talc'ing the belt as well as the rubber grommets and ends of the springs will help with adjusting (turning) the springs/suspension to tune the bounce. These inexpensive tweaks will make your life easier when you're setting up the suspension.
For transit screws: #6 coarse thread screw will work. I am sure there are others but, very limited choices where I live.
This Ariston RD-11S was equipped with a SME 3009 S2 Improved with removeable headshell tone arm but, and fortunately a Grace F9E cartridge.
This isn't my first foray into suspended belt drives. I've had many from various European, Japanese and American brands. Sadly, I never kept them, though I should have. Earlier in my "collecting" phase I was clearly in the Direct Drive camp. After getting the Ariston and setting it up, I soon realized I never really these suspended tables a chance. I think it was due to the fact a lot of them had finicky suspensions and none really used the SME style headshell.
I think the entire package has sold me: the look, the new springs and a solid arm with SME headshell. Though, it was a headache to get the springs adjusted until I made those tweaks.
Overall, I like it. I think the Grace F9E cartridge is well deserve of praise and I think I will get a new stylus from Soundsmith. It was already in great shape when I got it. Sounds better than my usual favorites, the Shure V15s and I even like the Grace better than my current ATVM95SH. I think the arm is quite good, though cartridge choices are limited. I do think it is still a solid choice. I could add a heavier headshell which I have! But, it's a lovely sounding table as is.
Side note: Getting a heavier counterweight, headshell and anti-skate can make the SME arm more flexible.
Honestly, this has changed my perspective on suspended belt drives! I want another one to play with!
Other minor things: I've added a finger lift (non OEM), new feet aluminum feet, new RCA plugs (old ones were gone and it was spliced with a ratty cable), oiled the motor and spindle bearings, adjusted the hinges and re-oiled the plinth. Looks fanastic! Runs smooth! I have other plans but, for now, I am extremely satisfied.
