How to adjust height of Eminent Technology ET-2 tonearm

If you loosen that screw, and adjust the mechanism to fall in the center of it’s range.......how does your cartridge look?

This will be our starting to point

As this point, you need to have you cartridge fairly level. If it isn't,, think about all of the adjustment features previously.

Let me know.

Dave - if you really want to try out that cartridge it is a very easy fix.

It's a SOTA Star Sapphire vacuum

I believe you have a wood plinth. This means they installed the ET2 with the aluminum sub plate so that the three ET 2 leveling spikes don't mark up the finish.

Remove the ET2 from its base in whole without the cart installed. Take the aluminum sub plate to any Metal Shop (when the quarantine is over). They will cut you a thicker aluminum piece, and drill the mounting hole to match. Then you have the opportunity to set up the ET2 properly.

Any adjustments made with the current install which is at its height limits will be sub - standard, as the tonearm was not installed optimally to begin with. 

I'm going to bow out in order to make the process easier. Listening to one person is better. Good Luck!

I've set up the ET2 on various Sofa turntables dozens of times when I was the importer here in New Zealand ( for both products ).
I've always been able to set up with the ET2 mounted directly on the Sota armboard without any spacer required other than the aluminium plate provided by ET.Sounds like you simply need to move the arc block up the post as per @ct0517 suggestion above. Have a look at the drawing he provided.

See the Bolt in the smaller Blue Circle.

It is important to try to keep the air bearing midpoint (inscribed line on casing) level with the record. 

As he also stated the purpose of the 3 holes for mounting the armtube is to get the centre of the bearing ( bearing spindle ) in line with the surface of the record. Then you position the arc block on the post, ideally with the VTA adjuster in the middle if possible which then gives you maximum up and down adjustability.

Thanks to everyone who has posted images, information, advice, and council. I've also received assistance from Bruce Thigpen, the ET tonearm designer. Short story is it's adjusted properly and working wonderfully. I really appreciate all the extremely helpful advice! I've learned a lot and have my ET-2 adjusted better than it ever has been. Thinking back to Oct 1986, I'm pretty sure my ET-2 was the first one they ever installed at my dealer. It's no wonder they may have made an error or two. I'll happily state, however, neither I nor any of my audio friends ever noticed the tiniest problem during playback. All is well. And again, thank you all for your time and effort to help me.
