Please help me identify these tonearms

Post by mrquant » 30 Mar 2018 01:48

Hi All,

Been cleaning out the turntable boneyard in the garage. Trying to put together some working tables for my daughter's friends who are getting into vinyl. I would appreciate any info on two arms that I don't remember buying. Probably from a mixed box at a yard sale.

First up is this nicely made piece with a straight arm:
40921
Note the spring. The headshell is removable.

Second is this unusual item:
40922
I don't understand this arm. Is this a unipivot design? I don't know anything about them. The arm sort of flops around like a ball and socket joint. It seems nicely made. The S-shaped arm is removable as is the headshell.

Thanks for any pointers,
John

The top one, I believe, was sometimes called All Balance, but there was recent thread about a turntable which it was partnered with. It was Danish, I think, and the company that made it became of was absorbed by B&O. There were japanese versions of the arm, but I wouldn't know how to distinguish them.
I believe the second one is indeed a unipivot, and I think it is japanese, but I can never remember the name of the company or companies that made them. Ikeda? Tokyo? Syntec?
Both arms have their devotees, and if in good shape, could be useful, or quite salable.

Thanks for the info! I think I'll McGyver up an arm board and try it out on the old 124.

Anyone have anymore specifics on the unipivot? I have been reading up and the conversations are pretty interesting. I guess I will need a collar for it and I'll need to figure out what weight or whatever hung off the little perpendicular post. Any pointers appreciated.

Best,
John

The second arm could be a Stax.

Indeed it could...a Stax UA-7 without its counterweight, base, cueing device and anti-skate mechanism. #-o

Mine is a UA-7/cf, same thing except a carbon fiber arm.

I have been using mine since 1976 when I bought the turntable. No problems with either. :o =D>

Thanks! Just looked at a few pictures on the web and Stax UA-7 it appears to be. Looks like I need to start a scavenger hunt for the missing bits. I assume I can live without the lifter. Do you happen to know if the mount is a standard size like a Linn or something?

The best I can do is that the installation manual calls for a 22 to 24 mm hole under the tone arm base. This is a simple sleeve with a set screw to adjust tone arm height.
To the best of my recollection, back in the 70's there was not a lot of standardization between different manufacturers mounting bases.

You may find the Stax installation manual in the vinylengine library helpful.

Good luck! :D

Looks like it was taken off a turntable, maybe a Sansui.

Identical to the one fitted to my Sansui SR-222 Mk1. Decent arm I'd say.
