454.0. "Cheapest/Best Linn LP12 upgrade!" by RDGENG::FRY () Mon Oct 25 1993 13:20
Purist alert! The following tweak is not Linn-approved.
I've got a Sondek/Valhalla/Ittok LVII, not Lingo-ed nor even Cirkus-ed. It's
had some new springs and rebuild a few years back, but other than that, just
garden variety (like, I suspect, lots of you out there). You know, the one
that was state of the art maybe 5 years ago?
Well, if you're in the UK (and maybe US people will also have it -- I
suspect so, but don't know, even though I'm a yank) and you go into
any Halford's auto centre you'll find MOLYSLIP, which is an engine
additive. Looks suspiciously like the black gunge Linn supplied me way back
when. It's black and light-to-medium thick, and you pour it into your engine
(does it have molybdenum (sp?) or something like that?). Note: It's not at all
thick like "motor honey", otherwise known as STP.
Well... you can also pour it into your Sondek (main bearing, that is, after
CAREFULLY removing the bearing, and cleaning with a tissue, and shoving a
twisted up tissue down into the hole to get all the old stuff out). Then, just
add about 20-30 drops, or whatever doesn't overflow into your turntable (I
didn't count accurately), put it all CAREFULLY back together, get out your best
and favorite records, a selection of UK ales (no smart remarks please --
I am perfectly sober), and put your feet up.
Now, of course you aren't going to believe this, but I would wager it's
getting on toward Cirkus quality, and
ALL OF THIS FOR 1p = 1.5c
since you use the rest of it on your car's engine, nothing is wasted !!!
And it's reversible!!! Just in case it doesn't work for you. Don't tell
Linn, and get them to do a lube job. ONLY YOUR HAIRDRESSER NEED KNOW.
There, I said it -- no hate mail please. But it worked wonders for
me! One day I'll get a Cirkus upgrade -- I promise.
YOUR MILEAGE MAY VARY. ;^)

Is there someone in the Reading/Newbury/Basingstoke area who would be
willing to try this lubricant? Please mail me.

| Without wanting to pour water on the idea - I'm as addicted to tweeking
my Linn as anybody - it's worth remembering that in the LP12 bearing,
the spindle is supported by two sleeves, one at the top and one at the
bottom. It is important that both of these sleeves are fully immersed
in oil.
Could it be that the original oil level was on the low side, and simply
topping up could have achieved the same result? The original Linn oil
was chosen on engineering criteria, considering the bearing
construction, temperatures it would run at, and so on, not on some
unwritten esoteric basis (which would probably be more fun but less
like Linn). The bearing and the oil were designed to work as system;
change a part of that system and you change its behaviour. Linn also
tested their oil by listening, as well as using engineering criteria.
OK, the Molyslip worked out very low cost, but the real thing comes
free each time an LP12 is serviced. It's probably not likely you will
knacker the bearing, but if you do you may as well get the Cirkus
upgrade ;-) which is more than just a different bearing anyway.
Just my 2p-worth.....

Well, it *could* be. I assume the oil doesn't go anywhere, nor evaporate,
so maybe back when Reading Hi-Fi was a Linn dealer, and rebuilt my TT,
they didn't put enough oil in there. I don't know.
Or, maybe it leaks out or evaporates? I don't think so, since there isn't
an oil slick under it...
I've thought about this, and considered this option that there wasn't
enough oil in there, because I think it works very simply like this:
It's not the platter which wiggles/wobbles, losing information. After all,
it's so heavy its resonance is very low. Rather, it's the arm/subchassis which
moves laterally *relative* to the platter, especially where there is any play
in the bearing, due to energy fed through the arm.
I imagine Cirkus is simply a better bearing, and more rigid coupling of
the new subchassis assembly. There isn't much else it could be.
Thanks for the food for thought.
