The under the bonnet engineering of the LP12 is not that good. Tiny inexpensive motors. Unsophisticated speed control. Wooden armboards, pressed steel chassis - which can be upgraded to an alloy one for considerable cost. Platter free to wobble relative to the motor. Relatively small main bearing. Relatively lightweight platter for a turntable relying on inertia to maintain pitch stability. Undamped, bell shaped metallic platter. Arm cable as 4th component in the suspension. Small springs...
The LP12 is the Linn modded clone of the Ariston RD11, which in turn is a copy of the AR XA, which is also similar to the Thorens TD150. The TD150 was the budget model in the Thorens line-up. The Thorens group made much more expensive turntables which unsurprisingly do sound better than the TD150 / RD11 / LP12.
'Fraid you got it a bit wrong, old chap! The original, in terms of suspension, was the AR, whose ideas Thorens followed with the TD 150. The Ariston built on both, but used a bearing that only one local company had the ability to engineer, and that was Linn. They later modifies and patented that bearing.
Never seen platter wobble on a Linn, nor on a Thorens, the engineering denies this. You also omit to mention the power supply, which was quickly changed by Linn when they produced the first LP12s. You also forgot the bracing, not to mention all the improvements Linn have made over the years.
I've worked on Lencos in the past. Rubbish arm, cheap particleboard, bottom held in with tiny screws that quickly lose their thread, which is a shame as the metal bar they hold in place is an integral part of the suspension. Build quality varied from turntable to turntable - oddly enough we found the Italian made versions better (sometimes )than the German ones. Rumble a major problem unless you got a good one, or were prepared to spend ages with that sometimes plastic, sometimes metal rim drive.
Whatever you may say or think about Linn, they consistently improved their turntable, and it is one of the reasons vinyl is with us still. The Lencos, Garrards, Systemdeks, Aristons not to mention the Japanese turntables are all long since gone.
