Uni-Protractor Set tonearm alignment


Looks like Dertonarm has put his money where his mouth is and designed the ultimate universal alignment tractor.

Early days, It would be great to hear from someone who has used it and compared to Mint, Feikert etc.

Given its high price, it will need to justify its superiority against all others. It does look in another league compared to those other alignemt devices

I just aligned my EMT 997 tonearm (NOS old design) with the UNI-Pro's 997 template to reach the full EMT geometry. I compared with common two Null-Point protractors and also with the one of EMT.

I did not reach such an exact and precise alignment than with the UNI-Pro. When I switched between Baerwald IEC and (for Monos) Baerwald DIN and back again to EMT you only have to check if you have put the Micrometer screw again on the right position.

Dear Tuchan,

Please excuse my ignorance, but how does one align EMT arms?
I have a 929 with TSD15 mounted on 930 and have been wondering if there is anyway to check/correct the geometry?

Thank you!

Just received it, very easy to use and fuss free. Another step forward for me. I would like an arc for confirmation on overhang though.
Dear Bydlo,
you may align EMT arms with the EMT alignment gauge. If you send me an e-mail I will answer and attach it. The better and more precise alignment you will reach with the UNI-pro coming with the 997 or 929 inlay. This is what I did. You can see it on one of the images on my page.

Ah, now I've got it Thuchan after seeing the pic (but the email is sent anyway :-)). I've missed that you use a different cart in the EMT shell. I thought you were aligning Tondose. Sorry for bothering
you&thanks for kind answers :-)

Best,
