What parts have you needed for a Clearaudio? Just curious. In nearly 15 years of Clearaudio ownership (Ovation/Innovation/Universal) I’ve only needed belts, and some bearing oil my dealer provided free.
As for upgrades, I got some pretty generous trade-in allowances on Clearaudio arms from Musical Surroundings in the past (Clarify -> Magnify -> Universal), the Clearaudio U.S. distributor.
A plain Innovation armboard with a 40 mm hole drilled in it for $900, with an 8 month wait. Replacement Master Innovation shipping boxes (& packing) also for $900. Everything ordered from Germany takes a long, long time to arrive. A 80mm acrylic top platter (to replace the delrin one), I think that was $1600 - 2K. The liquid pump in my Double Matrix Pro Sonic keeps failing, ugh very frustrating.
I also have a spare Innovation controller PCB which is good because I don’t trust the trimpots on my original one (always adjusting back & forth to try and stabilize speed). Can’t for the life of me remember what I paid for that but I’m sure it wasn’t cheap. I should probably also get a spare DC motor since I’ll be keeping this table for the long haul.
On the bright side it is my best sounding table :)
