Eminent Technology ET-2 Tonearm Owners

thanks for the head's up, ct0517. Mine is on its way. I've been wanting to replace mine ever since I bought my arm (used) a few years back. Alas, Bruce had no more to sell. So, this is a most welcome development.

The decision to use aluminum hopefully solves a problem I've had with using my et2: every time I adjust vta, the arm goes out of level and needs to be reset. I conjecture that the cause is the lack of rigidity at the contact point between the base and the two levelng screws. This holds especially for arms that have had their base abused by owners who overtighten the leveling screws and leave indentations in the base.

Yes
from my experience
The ET2 has three, well four areas that are sensitive to setup abuse by new owners, and those who are not aware of how it works.

The one you mention with the base and indentations from the vertical bolts from not being aware of how hard one has screwed those vertical screws down.
All leveling should be done after bringing them both up to reset. They should never have to touched again after that. if they do, the base is warped from abuse and/or there is a good possibility a users turntable is going out of level. check there first. Anyway the aluminum base fixes this problem so is welcome.
 
Very excessive force on the Post bolts and VTA block screws being over tightened and even closed.

I ask what kind of madman causes something like this to happen ?

The VTA block rack of teeth have been stripped by using it when the block was shut closed, and the VTA block case itself destroyed but excessive force on the bolts. .

A third being tightening the end cap I Beam cap bolt too tight could cause it to crack at the opening . I did this once years ago.

A fourth extreme is the gooseneck. Maybe tightened too tight and left on for years. A user when going to remove the armtube, puts incorrect torque in the wrong place and could snap off the cueing lever.

There is also a picture of it on my Audiogon system link. unfortunately the new Audiogon format does not allow me to link to it in posts - yet.  

Mine is on its way. 

Cheers

Bruce' new aluminum mounting plate weighs 39 grams on its own.  
40 grams with the three spikes.

The original mounting plate 23 grams and 24 grams with spikes.

If you guys recall, there was mention a while back on this thread that Bruce and his team were going to Africa with the BBC to test the hearing of Elephants using his TRW - 17 Rotary Sub. I've noticed some really cool pictures and footage of the trip to Africa have been uploaded to his rotary woofer website. I've linked them here.

Bruce' team then went with the BBC to Florida to do testing with alligators.
