Where to buy Linn LP12 Replacement parts?

I have a 30 - year old Linn Sondek. It is working fine! No need to put in replacement parts. I think you are worrying about nothing! Anyway, the LP12 is just a copy of the original AR turntable - which I also have. The claim that only a trained Linn expert can work on it is malarkey! It is a simple mechanism - a basic mechanical ability (screwdriver, pliers ...) will suffice.

The dealer told me: The springs are typically replaced every 3-5 years as well as the rubber grommets that they sit in.

I'll have to believe him on this one. Tried leveling it out tonight and it's not cooperating. I'm pretty sure he's right and some of the springs have gone soft. 

With Linn a search is best to use 'Linn Upgrade Parts' as this will broaden the Services to be found that off parts that can be swapped out on a Linn TT.

If the TT is a keeper for you, don't over look the idea of investigating / using a 'Phenolic Resin Impregnated Wood Board' as the structure to install the mechanical parts onto. 

@OP. LP12s are straightforward to strip down and rebuild. However, contrary to Jason Bourne's view, they are finicky to set up - and I've set up a lot of them. Some of the issues are - spring bolt perpendicularity, spring consistency and arm cable dressing. You are really better off taking it to a good Linn dealer and having them do the work.

What generation of LP 12 is it?

The great thing about them is upgrade potential. I’ve upgraded my sub chassis and tone arm the the top level and each provided a great boost in performance. I already had a new table with the upgraded bearing. It is quite surprising what an upgraded passive part like the sub chassis can make.
