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

I had a Kore installed in 2015 and the Karousel in 2020, so permit me  a few words. The single biggest bang for the buck improvement I have ever heard on my 23 years old LP12 has been the Karousel. 

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)

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

@dover  So, what happened?
