Linn Bedrok LP12 Plinth Upgrade

@daveyf 

It's basic engineering - you always put a smear of oil on both parts - housing and spindle to avoid scoring. If you rewatch the video when he first puts the spindle in the first time ( with no oil on the spindle ) he puts it in on an angle - scraping the top of the bearing housing.

I rewatched the video - few other items of concern

He drops the tonearm with delicate bearings straight onto the hard surface of the table - you can hear it clunk as he clumsily puts it down. I always place arms on soft pads to protect them.

Then he checks the vertical tracking force with the arm out of level. Most folk on this forum know that the tracking force will change when the vta is altered.

He should be checking the tracking force when the arm is level.

I also notice that when he checks the tracking force he manages to drop the lid and send it across the deck and almost wipes out the cantilever.

If this is the top Linn guy so be it.

Oh and he reckons the Linn should bounce evenly in a "pistonic" motion.

but of course it doesn't - watch the video - when he bounces the platter the side the tonearm sits on bounces much more ( the motion is higher and lower )than the other side - the whole thing is bouncing sideways, certainly not evenly let alone pistonic.

No If I spent $60k on a turntable I would not want that guy touching it.

YouTube video.

I felt l just had to watch this YouTube video after reading all this malarkey.

l will not get into a slanging match over what l observed, but it does appear to be a very lacklustre attempt to prove one thing or another that has obviously left more unanswered answers than it answers. As a tool for assembling this very expensive tonearm and deck it is very amateurish and unprofessional.

Recording and editing looks very rushed and calls into question why Linn signed this off. Quality control was thrown to the wind and appears quite comical. Everything looks like a ‘first take’ with no retakes.

Whoever oversaw the filming should maybe take note as the feedback just on this site alone can make them question if this YouTube link could be removed and recorded again. For this viewer it did not aspire much confidence in the senior engineer, and the production and can arguably damage the reputation of the brand.

@newton_john indeed, there are folks on this thread who assume a lot about the Linn table, you know what they say about folks who ‘assume’ things.

@dover My discussions with the mechanical engineer was in reference to the bearing, since you stated the shaft in the bearing would be “ as loose as a goose”.

This told me and was confirmed by the mechanical engineer that you really did not comprehend how the Karousel bearing functions.
As to the setup of the tonearm, I might agree with you, somewhat. The Ekos SE has very limited set up adjustments, one of the issues I see with that arm.

Where did you see the part where you say the lid is dropped? I did not see that in the video, nor did I see the part where you say he drops the tonearm carelessly onto the table..!!

On side one, or side two……

Everyone will be in one camp or another. I wonder if anyone’s opinion has changed? But harken…..l can see the light through yonder window glow to stop this discussion from turning very dark…..like the old foreboding ‘Darkest Africa’ expression in the 19th Century, l suggest a change to a lighter note.

Memories of, ‘’’Dr. Linninstone l presume?’’

Now how about an LP12 on a granite plinth……that would be less expensive. Anyone had the courage to try it?
