@daveyf I went last month and had an appointment with Thomas OK and did just that. I had more of a major overhaul of my LP12. I got the Karousel bearing, a new thinner felt mat, had the Karousel bearing installed on a Greenstreet Audio keel copy sub base that I had purchased in advance. I also changed out the Valhalla power supply and standard motor from the early 80's for a Radikal (Akurate level). I also changed out my Linn K9 cartridge for a Linn Adikt MM cartridge to work with my Bryston BP2-MM phono stage. I also got the Trampolin footer kit at the same time as well.
I spent approximately 5 hours at Overture Audio and Thomas worked through a checklist very methodically. It was really great to see the care that he takes setting up this gear. I had brought a thicker stainless steel top plate that I had purchased from eBay, a "Vinyl Passion Orpheus" that he tried briefly but the stainless plate was slightly too large for the plinth. I got to see how the original top plate is curved and how it flattens out as it is installed.
I also had purchased a new tonearm cable, also from eBay (both of these were British products BTW), a "pure silver tonearm cable" which he installed.
