Linn have ceased service support on many of their older products, these include,
Valhalla and Lingo mk 1 power supplies, LK100 power amplifiers etc.
We are still able to repair most faults on these units, so if you have a problem please contact us, we may be able to help.
Sorry but we no longer accept Linn cd players for repair / servicing as many key original parts are no longer available. |
Bearing Oil
I get asked quite often which is the correct bearing oil to use in an LP-12, below is a table showing all bearing and housing combinations used by Linn. Unless otherwise stated always use Linn black oil.
Bearing Housing
Bearing Liner

LP12 HISTORY AND UPGRADE PATH
Sound quality, as always, remains Linn's top priority. The following changes were made primarily as sonic improvements. However, in many cases these changes have also had an advantageous effect on manufacturing techniques, assembly procedures and easier LP12 set-up.
