Linn LP12 - Refreshing a Legend Empty Linn LP12 - Refreshing a Legend

Post by mfhoh Mon Sep 18, 2023 5:32 pm

It's been awhile since I posted and some friends have asked me to share a post on setting up and rebuilding  Linn LP12s which I have done many times.

This is photo story of a strip down and rebuilding of an early 80s Linn LP12, mechanics and tonearm, recently acquired from a friend. 

The rebuild actually started with the strip down and refurnishing of the "tired" plinth (which I did not take photos). The plinth is the earlier non-corner braced version with worn/aged finish but no major dent and dink or scratches. Unlike many LP12 of this era/age from our tropical/high humidity region, the integrity of the plinth is pretty decent/not compromised.

The original TT came with a white-lined bearing which I replaced with a used Cirkus bearing, clear lid and rebuilt Valhalla psu. I replaced all spares/comsumables. I initially wanted to install an Ittok LVII but ended up with the Ekos 2 just because the armrest borehole on the armboard has not been drilled.  

Here are the stripped down parts.
