Any Linn LP12 owners in So Cal get the Karousel bearing upgrade?


I live in north San Diego county.
Any recommendations on where I can get my Linn LP12 serviced and upgraded with the Karousel bearing?  My LP12 is vintage 1977.  It has the Lingo (Mk II) and Trampolin upgrades, but is otherwise original, including the bearing.
thanks for your responses!!

I learnt all I need to know about Linn when I restored my 1964 Fiat Bambina in the late seventies. Pulling the motor out to put a new gearbox in I must have undone many "locknuts".

Lo and behold, some years later, the Linn Doctor called in the early 80's - a new upgrade - LOCKNUTS under the springs to stop the suspension going out ! Only took Ivor 20 years to discover them.
@dover   There are a number of car mechanics on the various forums who also fancy themselves as experts at setting up the Linn turntable. All of them complain of the results that they get...I wonder why, hmmm. :0)

For the record I'm not a car mechanic, and I was a Linn Dealer for a while - at their request - not mine.

When they launched the Ekos, I had customers ready to go, and they refused to supply, expecting the customers to go to their distributor direct who also owned a retail outlet. Unfortunately for them my customers were so disgusted they moved away from Linn as well.
I stocked a range of top end TT's at the time.
