I also am the owner of Nokturne Audio, the North American importer and distributor for Lejonklou HiFi electronics and Harmoni equipment racks, both from Sweden. I also manufacture the NOKTable turntable stand, a refined update on the Archidee stand popular with LP12 and other turntable owners in the 90s, although I'm currently having to organize manufacturing of another batch of metalwork.
I do setup work on LP12s at Overture Audio and also occasionally travel to customers for setup, although that can get expensive. I charge $75 and hour and a full, precise setup normally takes three hours although it can extend to four if the top plate doesn't fit right as that requires close to a complete teardown to adjust. So generally $225 to $300 plus any necessary parts, most of which are relatively inexpensive. I am really looking forward to the new Linn Karousel as it is the first upgrade of the main bearing in 27 years and is the most important part of the turntable. Considering the obvious work involved in the new design I expect it to be a substantial upgrade and have ordered two for my own LP12s and a fair quantity for the store, many of which are already sold. Unfortunately the shutdown happened before we received our first shipment so I haven't been able to get my hands on any yet. When I do get one installed on my main LP12 I will report on the Lejonklou and Linn Club on Wigwam forums. Also there is a promo from Linn where you can get a free Karousel ($975) if you buy another $4000 or more of Linn products by May 22nd. Obviously this won't work for all but if anyone was considering the purchase of a Radikal, Ekos SE or Kandid any of those would get you a free Karousel, as would anything else Linn that adds up to $4000.
Thanks again for the comments.
