Why Linear Tracking never took off?

Poorguy, yes I think they are. The Revox is a very well made turntable with Swiss precision. Unfortunately they decided to use direct drive, which inherently puts the motor vibrations into the platter, even though most DD makers claim it doesn't. The only DD tables that were really good are the Rockport, which is all air-bearing, and the Goldmund. Before Psychicanimal jumps in here, I'll say the Technics SP-12 does a decent job with DD. And so does the Revox. It just doesn't do as well as a good belt drive table does. In addition, the Revox linear arm is not good enough to beat out a good pivot arm. This combination of things puts the Revox a level under a good belt drive like the ones you mentioned. Now I know that some people have these Revox TTs, and I don't want to be disparaging of them, but this is my opinion based on listening tests in the store I worked at, where we sold Rega, Linn, Sota, and many other belt drive TTs, and we also sold the Revox stuff. I did comparison listening on these things when they were brand new. My opinion has been stated above.

I had bought one of those expensive (at the time Linear tracking) I paid $1300 canadian for a Mitsubishi LT 20 their top of the line then and it is in excellent copndition except of course small scratches on the dust cover any idea of value? Thanks Jody

Jody, no I don't know what a table like that would bring these days. I suspect not alot.

Just in case anyone is interested, there's an auction currently on Ebay for an Infinity turntable from 1973 which has an air-bearing arm. Looks like this prototype never got off the ground but it looks interesting (in a retro kind of way). My other 2 cents... the ET2 arm was quite wonderful but the armtube had to be meticulously cleaned and setup for the arm looked daunting.

I own both a restored Yamaha PX-2 and a Sony PSX-800 Linear biotracer. They outperm anything else I've ever heard.
