Ancient AR Turntable with NO anti skate


A friend had me over to listen to his restored late 60's Acoustic Research turntable.  While listening, I noticed that the somewhat awkward looking tonearm had no anti skate.  Looking closely at the stylus assembly, it wasn't drifting or pulling toward the center spindle.  It seemed to track clean and true through the entire LP.  The arm is the original stock AR arm and couldn't be more that 8.5" or 9" in length.  I am just curious how AR pulls that off with such a short arm?  I have seen several 12" arms (Audio Technica for example) that dispense with anti skate completely but never a smaller one.  By the way, the table sounded wonderful and the cartridge was a Denon 103R.

Thanks,

Norman

@asvjerry "I'd go to an air-bearing arm in a heartbeat, but I don't have the disposable $ to go there."

Well, I just may have the bridge for you. Kidding. I use a Trans-Fi air bearing tonearm, cost about $1000. Actually, I use two: one for my Nottingham Mentor, upgraded to highest 2015 standard, and heavily modded; and one for my DIY air bearing TT. They bear a Mayajima Zero and Koetsu RSP respectively.

What I like best about the Trans-Fi is that it seems to be made for tweaking. Everything is exposed and accessible. You can add brass weights to make it heavier, you can experiment with damping, you can play with the air pressure, etc. Settings are dead simple and very stable. It uses clever engineering in place of costly machining. You buy it from the factory, not a distributor. And, when I bought mine, the owner himself went on a mission to make my installation a success.

You MAY be able to do better for 5 or 10 times the money, but, I suspect, only in terms of convenience. Opinion only - haven't tried the major alternatives in my system - but I don't see the flexibility in the other designs that I see in this one. See 'tweaking', above. 

Downside: the major downside is the name: Terminator. Other than that, azimuth is dead stable, absolutely repeatable, and intuitive, but it cannot be done on the fly, and is fiddly to adjust. Tracking weight is a little fiddly too - but rock stable and intuitive. That's all.

All in all, highly recommended, period. For the money, unapproachable.




@normansizemore "puny little motor"

Not to take anything away from masterpieces like EMT, but I differ. Maybe it’s my lack of masculinity, but I like puny little motors that I can boss around. I use motors that can’t even bring my platters up to speed, at all.

So I demand, and get, minimal vibration and minimal radiated EM field. And precision manufacturing is pretty cheap and easy with these puny little things.

Just how I like it. My opinion - that’s engineering. YMMV
