Eminent Technology ET-2 Tonearm Owners



Where are you? What mods have you done ?

I have been using these ET2's for over 9 years now.
I am still figuring them out and learning from them. They can be modified in so many ways. Bruce Thigpen laid down the GENIUS behind this tonearm over 20 years ago. Some of you have owned them for over 20 years !

Tell us your secrets.

New owners – what questions do you have ?

We may even be able to coax Bruce to post here. :^)

There are so many modifications that can be done.

Dressing of the wire with this arm is critical to get optimum sonics along with proper counterweight setup.

Let me start it off.

Please tell us what you have found to be the best wire for the ET-2 tonearm ? One that is pliable/doesn’t crink or curl. Whats the best way of dressing it so it doesn’t impact the arm. Through the spindle - Over the manifold - Below manifold ? What have you come up with ?

Thx for the info and legwork. That'll be very helpful.

I pulled the fitting off the top outlet and will try a few possible options this afternoon.

One thought... is it better to run the 50psi into a surge, then regulate it down, or regulate first, then surge tank? I have a couple of heavy-wall PVC pipe surge tanks and did have them upstream of a regulator in the past, so they can take the pressure.

Yah, I do already have a regulator, but I'm planning to setup both arms in separate systems and will want a 2nd one. I prefer to have the regulator near enough to the system where I can see it and adjust if needed. So I'll use the contacts you sent to get the 2nd one.

On the pump being ugly, I wasn't joking... it had seen some use, see here: http://www.ebay.com/itm/330896465118?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 .

I found the maintenance manual and opened it up... all of the sound-deadening foam is crumbling, need to find replacement. And the pump may not be fully secured on its mounts... will look at it closer this weekend and start some R&R on it.

I not only have 2 ET, but started with an ET-I back in the day! When I got that, I knew I had the arm I'd die with!

I looked a little more tonight and it is much worse than I thought... not un-recoverable, but needing a LOT more TLC than I expected knowing that it does run and produce pressure.

First the sound-absorbing foam has REALLY deteriorated. In the bottom, it is gooey & sticky & will be a real pain to get out and off all of the components there.

In the top, it is crumbly... will be easy to remove, just probably dusty.

Then the pump not only has broken loose, but has banged around a good bit and what I believe is part of the plastic housing or trim around it has broken into medium to small bits... of course, all imbedded in the foam.

I need to clean the foam out and off the pump and other internal components and take stock of whether that destroyed housing is a critical part of the pump's function (I suspect it helps in cooling the pump) and whether I need to replace it. Good thing is that I think I see the motor mounts (looks like they were not part of that housing) and if they are not sound, the pump has a standard mounting flange... I can always put it on a piece of MDF and mount that to the springs

And then the whole thing probably needs a rebuild.

Well, MUCH more work than I planned and expected, but that it runs means there is still hope.

It looks like the motor broke loose and banged around a long time ago, given how the pieces of the broken housing are distributed through the foam fragments. Shipping probably didn't help, but I doubt this much damage was caused in just one trip.

Greg -
I get ebay alerts on the Timeter as I am always on the lookout for a second one.
The link you posted - I remember that one and thinking - man that is rough.
For the shelf the motor hangs off to rot to the point that it came loose and it banged around makes me wonder what type of environment it was kept it and whether it was left in the rain for some time.
Water under the bridge now - no use thinking about - this is what I would do.

I'm assuming the motor and fan still operate ?
Remove all insulation as you say.
Put in another shelf (it slides in and out easy enough) and remount the hanging motor.
Once this is complete and this part is very important.
Get an empty regular hand size water bottle.
Fill 1/3 with CLR. insert the water/moisture spring loaded exhaust nozzle into the bottle.
Leave overnight.
Next day you will see what kind of environment it was run in by how much crud gets dislodged into the container.
Remove the bottle and cap it for reuse later.
Start it up and the pump will blow the remainder of the crud out through the nozzle if any remains.
The pump will now purr better and run cooler if the nozzle was partially clogged. Turn it on and see how hot the motor gets.
It is hot to touch normally. Make sure there is no obstruction on the bottom under the fan.
The air exits from the bottom.
The housing shape above the motor (that broke to pieces on hours) helps the air run through shelf opening and by the motor - there are wide slots on the top of the upside down half bowl shape to help with this. By removing the insulation you will also have helped cooling as well I believe.
Let me know how you make out.
(that broke to pieces on hours)

should be (that broke to pieces on yours)- wish there was a way to edit.
