Eminent Technology ET-2 Tonearm Owners

Hi Tequila

been up north trying to find HD Satellite 82 through a mess of woods.
talk about frustrating. nothing in Audio so far matches this type of frustration when you don’t have a clear line of sight., and mosquitoes biting at you.

re: VP0140 pump

I still have a couple of those stored away.

For a simple pump the order would be .

Pump =====> surge tank =======> regulator / filter ======== ET 2.0, ET 2.5

This ensures the PSI and Filtering is maintained closest to the tonearm.
If you have gone through this thread you know we are all running different pump systems. For this reason and others when buying a new ET 2.5; it comes with no pump but Bruce will help you acquire one.

Pumps that have adjustable PSI will also have their own internal regulator. So it is possible to have a couple regulators on the line - start and end. A long air line of say 50- 100 feet coiled up also acts like a surge tank and smooths out the air pulses.

Tequila, your moniker brings up Mexico. Anyone buying a used ET2 from Mexico should give the capillaries a thorough cleaning due to air quality. Sonics are greatly affected by quality of the air. if they (capillaries) are partially blocked you will need to run a higher PSI to make it work. This is a band aid and the sonics will suffer. Any used ET2 purchase should be cleaned out.

The quality of the air going into the arm is most important and affects the sonics greatly in two ways.

1) Clean dry air keeps moisture carrying particulates from clogging up the pores of the capillaries.
2) Stable pulse free air ensures great sonics - you will know when you hear this. Music flows like from a water pipe - a relaxed presentation.

fwiw
I used to have a VPI mkIV with my first ET 2.0 many years ago. The springs can be a PITA as they have a tendency to go out of level easy. Replacing the springs with pucks helped, but then you need to introduce different turntable footers.

My 2 cents. hopefully others can offer their opinion. Welcome to the thread and AudioGon.

Thanks very much for your reply!

regarding the 30 min operation warning on the Medo. 

The pump has heat sinks much like a Solid State Class A/B amp.  It does get hot quickly. A small computer fan placed next to it alleviates this limitation. It can be run for hours and never gets hot.

Hi ct0517,

Thanks for your help! Actually I located in China rather than Mexico although my web name may have given you the wrong impression. :P

I have tried 3 pumps so far
1. Medo VP0140 200V (Directly to the 220V supply) which came with the Turntable and Arm.
2. Medo VP0140 24V (Wired through a 30W 220V-24V transformer)
3. Medo AC0210 115V (Wire through a 50W 220V-110V transformer)

So far I hook it up like Pump->2 Filters-> (Gauge) ->Arm

1. gave me about 2.5PSI at the arm, I ran it for an hour without problem. But 2. and 3. gave me basically no pressure, I have no idea why but they do seem to work perfectly and pump out air. There are a lot of 2nd hand Medo pumps that I can buy here (about 20 to 30USD each), so I just ordered two Medo 0110 (which spec to 14psi) to try, and the shop promise me that they are tested and work well. So I will try and see the results in a few days.

Due to personal reasons (young kids, job, moving locations), I have been away from the audiophile hobby for 7 years and now I am back (I still have close to a thousand records in my closet). Although I have not tuned my system yet but I am happy with the result and I can finally sit down and listen to some music.

Cheers

And also, I found that actually I bought another used ET2 (without TT) years ago and it was sitting with my LPs, which I forgot, and now I have one running and a spare ET2 too :)
