AMG Turntable Opens Up Bearing, We Have a Look
The $17,000 German AMG turntable/tonearm combo imported to America by Musical Surroundings is a deceptively simple and compact product, but to really understand its unique, high-tech engineering requires a look inside. The photo of the cutaway bearing shows the oil bath in red. Note the large diameter polished spindle shaft and large surface Teflon thrust pad. The designer claims thrust ball interfaces are not a good idea. That discussion will have to wait until a review, coming to Stereophile in a few months.

AMG Tonearm Details
I thought you might find interesting the AMG arm’s unique bearing. At the very top you can see two cylindrical vertical posts. The protrusions atop them fit into the top of the tonearm housing and are secured to it.
The very small diameter wires between the cylinders and the bearing body are the vertical bearings. There’s no bearing “play” because there’s no bearing in the traditional sense.
The horizontal bearing system is a more traditional, but very long roller bearing. The adjustment being made is to a magnet that sets anti-skating.
Like the platter bearing, the designer has come up with a unique, yet very sensible solution to tonearm bearing design.
Here’s Something You Don’t See Every Day!
Pictured from left to right: Touraj Moghaddam, former Roksan turntable designer, Franc Kuzma, who needs no introduction, and AMG designer and former machinist for Brinkmann turntables (as well as a former Lufthansa pilot), Werner Roeschlau.
All were in the room to examine Mr. Moghaddam’s new $35,000 tonearm. Yes, $35,000. It’s a one-off design exercise but if anyone want’s one, Mr. Moghaddam will build it.
More about the arm later, but were you to see the machining excellence and unique design, you’d at least appreciate the design talent and machining excellence required to produce it.
