More Mober For Linn Sondek LP12

Mober sub-platter for Linn LP12 tur table, though Cirkus compatible, I much prefer the sound when mated to it's intended partner, the Mober bearing.

In my last story about the Mober sub platter, as started with my desire for the latest Linn Karousel bearing upgrade, but the prohibitive pricing of Linn lead me to looking else where. Along came the Mober items purchased from Edmund Chan who makes these Mober products & ships out of Hong Kong. 

Doing the Mober bearing upgrade, much like the Karuosel, requires the Vahalla or Hercules power supply board to be moved out of the turn table, in to a separate external box. That means my Hercules II Gold power supply board will need a box to be housed in. Fear not, Mober has a solution in the form of a Mose kit!

In the process of reading up on the Karousel vs Mober bearing, it would seem to me that Edmund had started putting the Mober bearing in to the market 2 years ahead of Linn! However, the emergence of Karuosel has made Mober to introduce an improved version with collar mount option, compared to the 3 point mount of the previous design, as in Linn's Cirkus bearing. Competition does indeed spark innovation in this case!

Now let us go through the build pictorial:

Mober(left) bearing vs Linn Cirkus(right). Notice how much bigger the Mober bearing is at the bottom? The Mober bearing also offers collar mount, which I feel in much better than 3 point mounting, as the stress points are even out with collar mount.

The bridge comparison, left is the Mober supplied unit which came as part of the bearing package. Compared to the Linn supplied unit, notice the bearing thru hole in the center, which is much bigger diameter with the Mober unit. Also note the heavier steel gauge used, and that improved wire hold down design, which is far more rigid compared to Linn's fragile looking P-clip, not shown here.   

On the back is similar story, the Mober parts exudes quality build that Linn can only dream about!

The Mose casing to house my Hercules II Gold power supply board. This 2U design casing is aluminum extruded and finished in satin black for an overall high quality look & feel.

The back panel of the Mose box, a multi pin socket provides easy & removable wiring option from the turn table.

Even the IEC socket provided with the Mose is a gold plated audiophile grade item, Mober has put in much thought to his products!

Inside the Mose box is an added AC board for LED indicator at face plate, and rerouting all Hercules II Gold cabling requirements to the multi pin socket.

Fitting of Mober bearing commence! The Mober bearing is first collar mounted on to the Linn Kore sub-chassis. This is followed by the motor & 33 & 45 rpm switch on the top plate.

M for Mober!

The wire hold down clamp as seen here in white is much easier to work with, compared to Linn's P-clip design. Just lift the clamp high enough to slip the cables through, then tighten that hex key.

The finished project, with Mober's L shaped power supply board to accommodate the much bigger bearing. the multi pin cable from Mose box shown earlier is attached to this L-shaped PS board. Also seen here with tone arm cable & multi pin cable being clamped down respectively.

And lastly the whole turn table assembly sits on the Linn Trampolin II

The finished project, with the newly Oak finished plinth. This project is like a total rebuild, and since I am at it, I also swapped the Koetsu Black cartridge to serve on the Linn LP12 turn table.

The sound of the finished project is excellent from the first needle drop! The initial sound was fast and exciting, with little to no back ground noise. LP surface noise is largely reduced as well. The bass is now truly powerful and tight! The Linn finally has the bass power to rival my Kuzma turn table. No more  Linn's flabby, "mong cha-cha" bass of the old. The Mober bearing package, with it's sub platter really brings the Linn LP12 detail retrieval ability & clarity to a whole new level. The good part is Linn's much fabled mid-bass is now clean, and doesn't intrude and cloud the male vocals anymore. Treble is much extended, airy and clear like a breath of fresh air! The noise level after the Mober bearing & Mose kit installed is near zero or un-audible now. After a few days, as the 3 springs that suspends the Linn settles down, the treble begins to soften a touch, and some semblance of the Linn LP12 sound character re-emerges, but just enough to remind you that this is still a Linn LP 12 after all.

I feel the Mober kits offer very high value for money in each & every way one looks at it. The Mober kits are well made, with good materials, high quality finishing and much design details that only someone with an intimate knowledge of the Linn LP12 can think of. Best of all, the Mober kits are much, much more affordable than the Scotland made stuff, yet suffers no sound penalty or build quality. I think the Mober kits may somewhat sound a little different if compared to using all Linn parts catalog, but on the whole, Edmund Chan is a person who understands the Linn's engineering philosophy well, and doesn't stray too far from where the apple tree is. I now have much respect and high regards for the Mober kits. If you have a Linn LP12 turn table at whatever vintage, do give the Mober kits a go!

Given today's Linn aftermarket diversity, and Linn's endless catalog of up grade parts, I can tell you there no 2 Linn LP12 in the world that is exactly same anymore, after leaving the showroom! A celebration of diversity I guess.....
