Linn Sondek question


What is it about a Linn Sondek LP12 that requires it to be tuned up?  I was at a Linn specialist recently and was amazed at the amount of Linn Sondeks he had just in waiting for "tune ups" or whatever they needed.  There must have been at least twenty.  So, how often does this have to be done?  Is it the springs, weather conditions etc.  I never see other tables requiring this kind of attention for what seems to be required on a regular basis.  Can it be done by the owner?  Seems like a lot of fiddling.  The setup that was there sounded great.  There is a specialist on youtube that posts many Linns and the sound quality is fantastic, but at what cost?  Like I said, I have never seen that many tables requiring attention in my life.  So what his the thing with these tables?

It's British (or Scottish, actually).  Have you ever owned a car with a Lucas electrical system?  In this case, it's the spring suspension that apparently requires attention at intervals.  A cynical interpretation would be that the "tune-ups" are purely for psychological effect; when the owner gets it back, he will convince himself that he is hearing a huge improvement, whether or not that is the case.  But I'm not saying that's necessarily true.
Apparently, if you push down the spindle and let go, the suspension should bounce a number of times straight up and down, symmetrically. Look at the arm board and ensure it is level all the way around and that it bounces in sync with the platter. I have never had mine adjusted except at purchase from the dealer and it is still 95% in tune 30+ years later. I'm not saying that tuning doesn't help but I think it might be a bit hyped. However, changing arm boards and tonearms may require re-balancing.

How do you know?  I've setup a lot of Linn LP12's and I would wager to bet that yours is in need of a tuneup, (probably many years ago).  You would be surprised how much of a difference it will make.

These things age and go out of alignment very gradually over time.  Our ears get used to this gradual change.
