Linear tracking turntables, whatever happened?


Curious as to the demise and downfall of the seemingly short lived linear tracking TT.
Just from a geometry point of view I would have thought a linear arm should be superior to one with a fixed pivot that sweeps through an arc.
Obviously there is much more to it than that, sort of the reason for this thread.
I am genuinely interested in trying one out for myself as well.

Understanding these design differences will go a long way towards setup of both tonearms. If anyone is toasting carts on an ET2 they have no idea how to set it up.

Sounds to me like your dealers were Personality Type B...8^0.

Looking back on it, I think you are right.
So the Harman Kardon ST7 with the Rabco arm is likely to be one to be avoided. I guess HK bought out Rabco in the seventies and thought this TT would be a good idea
@terry9---say, what pump do you use with your Terminator? Have you also incorporated a "surge" tank? Just a regular ol' 1 gallon plastic jug? I'm about to mount my Terminator (which I had Vic fit with the last of his silver wire, straight to a pair of WBT RCA plugs) on a VPI Aries 1 I got specifically for use with the arm.
I use a HiBlo pump from Pets&Ponds. Model 60 I believe (massively overspecced because I planned to use low pressure for other uses). I use a 1 gal plastic jug filled with cotton balls, with a long piece of perforated plastic tube feeding air to the inside of the jug. Then a Fairchild precision regulator and a medical blood pressure gauge to get me down to the 10-50 mm of Hg range (sub 1 psi). I finish with a 5 gal Jerry can surge tank.

Vic's silver wire is very nice - very pliable, very euphonic. I use ETI connectors myself.
