Does Anybody Know This Tonearm?

Mitchell Cotter wrote a paper for AES back in the 1940's that described his idea of the perfect tonearm. In 1979, Jim Winey built it. It was called the Magnepan Unitrac 1.

It is a tonearm worth investigation because it is a sleeper in many ways. A currently manufactured tonearm that has many of its characteristics is the Spiral Groove Centroid.

A little touchy to set up?Come on it has VTA on the fly,that's half the battle.Ok you got me on that bucket of shot.Really the most negative thing I would point out is the tonearm cable which has a unique termination plug making life difficult when you need to replace it.

Love my Maggie arms! Great with high compliance carts.
That Amphenol plug(222-11N07) was discontinued in the 80's.
Not an easy item to find, but- in reality; it shouldn't ever
have to be replaced. I bought a couple extra arms, so I
could cannibalize one, make an adapter and
use
a Tricon Analog phono cable, instead of the old one. This
is the only supplier that I've found to have any NOS plugs
left(to the tune of $90+): (http://www.semiconductor500.com/store/index.php?main_page=product_info&products_id=23382&zenid=062191ae763593d8f853cd31b69cd84e)

I've been happily using a Magnepan Unitrac I for nearly 30 years, and I have no plans to switch to anything else in the foreseeable future. For the most part, I've used it with Grace F9E series cartridges, first the F9E, then the F9E Ruby, then the F9E Ruby retipped by Soundsmith.

BTW, the "logo" referred to in the OP is not actually a logo. On my tonearm the word "Unitrac" appears there, in black lettering on a light grey background. Apparently that label is no longer present on the arm that is pictured.

Hey Al- If you ever get the itch to go MC(and own a phono stage with enough gain): try a Dynavector 17D3. It's magic, on a Maggie arm.
