Presumably you mean my comments? Zink is inherently prone to oxidisation. In the worst case it results in a powdery white residue but more often it means the shiny edge of the platter becomes dull and eventually a flat grey in colour*. To counter this Linn clear lacquer the outside of the outer platters, but this thin coat has been known to fail over time. If you look on the Linn forum you will find many threads where people have repolished the edge of their platters but because of oxidisation this has to be redone on occasion (as with brass for example).

* This is why it is recommended you do not touch the inner platters running or mating surfaces - the moisture in your fingers is likely to encourage oxidisation.

You are grossly misunderstanding me again, I object to being fed BS, I have no idea if it works - I have not tried it.

As for real metal-metal contact - a lot of lubricant experts will tell you that if the lubricant is correct, you will not get it. At the very simplest and oldest level, look at lithium lubricants and how they work. look at the most specialised lubricant websites and the like and modern lubricants will still provide a film, albeit a mono-layer (and that is all that is needed) between "mating" parts under phenomenal pressures.

Boy oh boy! As they say in the classics ... you can lead a horse to water but you can't make it think (to drink)!

Roger, Mark ... stop wasting your breath (or should I say blood sugar - as it's that which powers your typing fingers!). I suggest you are going to have a better chance of persuading a 'flat earther' that the world is actually round ... than getting Vinny to try out a Tranqu!

LLLOL - it is not that I do not think - it is precisely that I do, and if I suspect BS, I know enough or know where to look to challenge it.

As for trying a set of magnets.. who knows......I can think of lots of better things to spend 400 on - yes - 400 for some magnets........................ now that IS funny

So, Vinny, you think you are one of the special ones - one of the cognoscenti who have figured out (from knowing the theory) that the Tranq must be BS? (Whereas all we happy buyers/users are poor benighted folk - who are either stupid ... or ignorant - and incapable of doing a simple listening comparison?)

Mark has shown remarkable restraint. What a true gentleman. I walked away days ago.

I don't know what percentage of the vertical mass of the assembled lp12 platter is relieved from the bearing contact point by the tranquility, but its significant. The amount of force required to get the magnetic elements in the tranquility to touch when aligned as when fitted is defo in the order of kgs.

Though I've not measured the tranquility, I have measured marks own deck with his own maglev in place and recorded both noise tracks and silent grooves. The reduction in noise amplitude was between 3 and 4 db, centered between 15 and 60Hz with a bell curve distribution.

So there's no doubt that eliminating the bearing contact pressure reduces background noise, I've measured it and heard it. I'd suggest. that the tranquility provides a proportion of this reduction.

I have the Mober bearing, it's a total piece of shit, utterly unusable. Ball races have no place in a turntable bearing. Its the worst of all worlds all the noise of a ball race compounded with the noise of a point contact bearing with zero magnetic support.

I have an old Linn bearing, its noisy. I put a glass filled Teflon pad in it, it was measurably less noisy. What should I conclude from that about the contribution of a worn point contact to bearing noise? Should I have expected the speed of my deck to change?

Maybe less theorizing, and more measuring...

I have asked for data to support the Tiger Paw claims on the website - and so far........... we have precisely.............. none.

Work it out boys..............................

It does I've measured it.
