Default Linn LP12 and SME 3009/2 improved.

I've been meaning to write this thread for a few months but l got carried away with listening!

Following on from this thread https://www.vintage-radio.net/forum/...d.php?t=205473

I'd bought new rubber suspension and springs, a new acrylic arm board and all the fixings, ie miniature bubble levels, SME protractor and a VTA gauge.

The first picture shows the original underside. Third picture is the cutout required and pic two the new arm board, arm and new cables.

Picture four is the sharp end of an Audio Technica OC9-XML MC cartridge!

More to follow...

After mounting the arm on the board and the board on the deck came lots of checking with the bubble levels and fine-tuning the trademark "Linn Sondek Bounce". This was made easier by replacing the thin fibreboard from my Sound Organisation wall mount with 10mm MDF, drilled to allow access to the suspension.

The tracking force was set to the recommended 2 grams to start, then the protractor was employed to set up the overhang. This took minutes only thanks to the SME sliding base.

VTA was next. Undo grubscrew B, rotate arm, tighten B, undo grubscrew A, rotate arm back, tighten A. Repeat until the cartridge is parallel to the platter.

A cork and rubber Matt replaced the felt original, deadening the the platter.

The Quad 34 mm module was replaced with a moving coil module.

Using the HIFI News test record, the tracking at 2 grams cleared the medium hurdle without batting an eyelid and was almost perfect on the "torture track", so I left it at that.

Thanks to Alan, ajgriff for doing such a great job on the restoration of the arm, and to Steve, stevehertz for pointing me in the right direction re cartridge resonance.

You have been busy Ken and it’s heartening to see the 3009 in its new home especially as it languished unused for such a long time, probably decades.

Clearly a lot of effort has gone into tuning the Linn and setting up the new arm/cartridge combination. I believe that the Sondek was previously fitted with a Linn Basik Plus arm and a Goldring 1022GX moving magnet cartridge. It would be interesting to know, subjectively of course, how the new set up compares to the old?

In a word Alan, better! I pulled out some of my old favourites from the 70's and 80's that I'd purchased new as they were released.

I found myself hearing more "atmosphere" around voices and backing vocals; on the Kate Bush album "The Dreaming" there's a track called "Night Of The Swallow" where the lead vocal opens out from close to the microphone to a large room. I'd never heard this part before as the chorus that follows immediately afterwards had always drowned it out using the Goldring and Basik combination.

With Tangerine Dream's "Sorcerer", the complexity of baseline drones are easier to follow as they are not overwhelmed by the other components of the piece.

If this all sounds a bit audiophoolery, it's only because it's so hard to explain. The whole thing seems to have solidified, lost something that was blurry and indistinct, come in to focus.

Hope that's helpful Alan, thanks again for your dedication and skills.

Doesn’t sound at all like audiophoolery to me Ken. Your description suggests a significant increase in clarity as a consequence of reduced distortion. It’s likely of course that each of the physical improvements has contributed to more faithful reproduction to a greater or lesser extent. Pure speculation on my part but I would guess that the moving coil cartridge is the single biggest contributor in terms of enhanced musical enjoyment.
