Eminent Technology ET-2 Tonearm Owners

Hi
I am new here and in need of some tips
I have a ET2 that Im trying to upgrade to a 2.5
but have problem running it on 7.5 psi. It was marked mpm
I have a felling that is a bit clogged. What is the min working pressure for a mpm?
Any way to clean out the hole think there can be a bit of oil in them. This have a NOS upgrade kit came in plastikk bag and was a bit greasy. Have clean it a bit with alcohol
Got it to a point where it works "just" 95% of the time.
outer and inner section can some time be problematic.

I have Wisa 300 pump makes to much to noisy and need to be move that is most likely to bring the 95 down to 0.
there will be a lose in pressure even in a stiff tube over 30 feet.

But before I work my way true all the pumps I need to be sure that I have a working 2.5

any tip how to figure out this one

With regards

The way I level is by using test record with blank track.

I can't see how to setup corectly with out one.

Will a London decca gold fit on 2.5 alu ?

Once more am I in need of the knowledge of this community

I have decided to change turntable. My trusted TD125 is going into retirement and a Micro Seiki RX/RY/RS/RW 1500 is going to take over the job.
This is raising some issues. I'm now in need of some sort of drawing for a armboard to mounts the ET2.5 on.
I have access to knowledge and equipment to making the board board. (CDC -)) I even have it options to make it from whatever material that is optimal I guess titanium is a bit overkill. LOL

I've seen this done before on pictures I'm not sure which armboard that's been used. I have an option to use both one or two posts. I'm suspecting to post board will be the best 
My plan is to mounts and acrylic shield on the backside. 

I don't have access to special mounting tool (the Jigg) 
So if anybody have control over the geometric positioning that will be of great help
Also Interesting in hearing what kind of mounting, what kind of material that will be the best.
 I'm planning to put two more arms on so this is going to be a tree arm rigged Rx-1500 ;-)))))))))))))))))

Well Chris with cant fine any armboard that is even close be able to get the distant right AX-3 is the closest but I think I either with touch the plate or get too great distant from the spindle. I know I can angle but then I lose option to mount all three arms. 

The problem is not to "walk the line" the problem is walk the line without interfering with the other arm's 

This mean that the onboard has long and curve around the plate. Then the mounting area has been big enough to support the base so all the spikes "hit something"  

The second part of the manual on Bruce' websites will be a great help

I'd hoped that somebody had a design ready for this so I don't have to redesign the whole thing from scratch. 

The problem with them RX1500 is that the mounting posts is so close to the plate 

I know that the ET 2.5 is going to be the king. No problem admitting to that.

The thing is that I love to have a setup where have the option for some variation and to "Just play some something"  when not really" listening" with out using hours on the High end pickup.

Cleaning house on high end time is vast of hours LOL

Second ET 2 sounds like a crazy good idea

Thanks Chris 

I did see that picture but misted out on the discussion 
I have to read true that string. 

Have a feeling that the RX1500 is going to be a good stable platform for my ET2.5 ;-)

5000/8000 even better but $$$$ so that have to wait for now Think hard to get to.

Well no big surprise that I have a alert on ET2 on ebay ;)))))))
but my problem is that I only need the arm (second ))))
no pump 
by the way I have a  wise air pump left over more or less new 

Moved the air pump up in the loft with tank and 10 m hose down 
runs it at 14 psi and the wise pump not able to do that job. so now I use a big ugly and noisy air brush pump. Cant hear it and air stream very stable The long hose help a lot i think. 

But thing the micro seiki need to come up first.so all safe for some time ;-)
All part for the test rig ordered. 
planing to start disassemble and CLEAN the arm next week. 

Any in here with the high mass arm ?? 
any improvement on 12-10 comp cartridges?? 

I ended up using all 40g leads on a 10g cartridges and with 2.5 g tracking
the lead mounted on the outside of the I-beam and the rood pointing inwards the I end up mid on the I-beam scale 

Harry, 

I have a London Decca Gold, love that sound. If it's good "old" sound well that can be a way to go ;))))))

Harry 
I used it on a TD125 
A bit hard to setup but.. when there, well then something special

yes Slaw since the moment of the needle is direct there is a lot of forces that have to be damped. need high mass tonearm.
