Linn LP12 turntable


I was in my favorite audio store yesterday talking turntables… Rega P10, MoFi MasterDeck etc, when he stated he had a Linn LP12 he was selling for a customer at $2,400 & the customer had $14K (with upgrades) into it. Intriguing, but knew nothing about Linn. After my research, people seem to love it or hate it. But it is installed in many fine audiogon systems. 
I would like your thoughts and recommendations. 
I have asked the following questions of the dealer: 

1. Date of production 

2. Upgrades that have been added 

3. Power supply / tone arm

4. Condition 

5. Recently serviced

I have not yet seen it, but it is there now. What other questions should I ask?

My current analog system: 

Pro-ject 1xpression carbon classic with Hana ML

Rega Aria

PS Audio BHK pre

Simaudio Moon 330A amp

KEF R11’s

Advise would be greatly appreciated.

Attached is the note I sent to my dealer. I think I covered all your recommendations. 

Jon, thanks! I did not expect a reply on your day off. Based upon my research, if the right options are installed it is a great buy. 

Those options are: 

 -Karousel bearing

- At least a lingo PS… Lingo 3 preferred. If it still has the Valhalla power supply, it is not compatible with the new Karousel bearing. Most people believe the Karousel bearing is the most important upgrade. 

- Kore sub chassis 

It would also be helpful to know the new tonearm & DOM. 

Four other question:

1. is the dust cover permanently attached, or is it removable. Removability is important based upon placement. Or it the Rega or Mitchell covers fit, that would be ideal. 

2. Would you allow me to try it at home, not only for sound, but understand it is prone to foot falls, although the new trampoline helps with that. 

3. I know the cartridge has a lot of hours on it, but what cartridge is it. 

4. You are not a Linn dealer but it appears you have done the service on this TT. From my discussions, it appears the skill of the technician is crucial. 

This could be an excellent purchase but I don’t want to fall into the Linn ‘money pit’.  

The attached is my audiogon discussion on the Linn. I do Audiogon forum discussions on all my audio purchases.

You have been excellent! Thank you for bringing this Linn to my attention. See you Tuesday. Thanks!

You are correct. I was conflating two thoughts. One that the suspension is made to dampen smaller higher frequency vibrations and my experience that rapping on the top with unbelievable force would not result in a skip (or sound) but walking by the turntable would. 

I loved my Thorens TD124 TT: 9lb cast platter, Best BASS I ever got out of a TT (shure v15vxmr beryllium cantilever micro ridge, sme 3009II).

HOWEVER, the main bearing of the TD124, a magnificent thing, is susceptible to vertical vibrations, and my wood floors are springy, thus 'goodbye sweet thing goodbye'.

I give Linn credit for all it did for TT/LP when they were essentialy alone in the world, but if you don't get excited every time you see it, why?
