Afternoon guys,
just wondering if anyone can give me some tips on the following.
I've upgraded my Linn LP12 with a Mose power supply and Mober bearing. I'm using a pre-cirkus spindle/subplatter (which I was told is fine).
Installation was really easy, much easier than I expected and is testament to the designer/supplier (Edmund Chan).
Anyway, after installation I can hear a small amount of grinding from the spindle in the new bearing if I put my ear a couple of inches away from it. I've used the correct amount of oil and it seems to be spinning freely enough, its just the sound wasn't there before with the old bearing in place.
Once the platter is on with the slip mat and its rotating the sound is certainly less audible but if you listen for it is still there.
I have only "loosely" set up the turntable regarding springs but I know its not far off and I don't think it would have any effect on this issue.
I've spoken to Bigbird (Karl) of this parish who has been super helpful in general to me but I just wondered if anyone has any tips/suggestions?
I can see you can secure the bearing in slightly different positions depending on where you secure the 3 retaining screws and I'm wondering if this would effect it?
Maybe due to the ball race design of the bearing there is a small amount of friction present as the bearing does hold the spindle slightly tighter than the old bearing.
I'm also wondering if a Cirkus or SSP12 platter upgrade would help.
All suggestions welcome!
Cheers,
Chris
