Eminent Technology ET-2 Tonearm Owners

Hi there,

I recently acquiref a used VPI TNT MK3 with ET2 arm. It came with Medo VP0140 pump, two filters and an Airtech surge tank.

Since the VP0140 pump is rated for 30mins operation. I planned to get a used Medo 0201 pump and fit a pressure regulator as well. Then I will place the 0201 in an enclosure.

My question is the sequence of hooking these up.

1) Pump->Filter->Regulator->Surge Tank->Arm
Or
2) Pump->Filter->Surge Tank->Regulator->Arm

Which one is correct?

Thanks
Tequila

Thanks very much for your reply!

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 :)

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

I finally got 2 Medo 0110 pumps to try. Both of them give me about 5psi at the arm. One of the is quieter.

My plan is to build a box for it using MDF and lined with foam. For now this is going to be a closed box with no fan, so it could create some heat issue. But I worry that if I cut out some vents for the cooling (plus adding a PC Fan), the noise would be a bit too much as I need to place it in the living room where I also have the stereo.

Will give it a try coming weeks.

Hi all,

Haven't posted here for a while. I acquired a local China brand air pump (FFYX which made its own air bearing tonearm and turntable), not cheap (around 600 USD), but its super quiet and cool. It provides about 4 psi to my ET2. I think I will stick with this for a little while.

On the other hand, my vinyl system is continuously being tweaked. While I rebuild my ET2, I got the new Aluminum arm base and clamp from Bruce, and also added the VTA dial. Still tuning.

Found a used Bright Star Air Isolation Platform and a custom made sand box for the VPI TNT, and look forward to have its current owner to ship to me.

Cheers

Hi Dave,

I haven't tried the Brightstar Platform by itself. When this is combined with the sand box as you can see in the thread, I like the sound. Good solid sound stage and feeling very low noise floor.

The entire platform, sandbox and TT/Tonearm came from a friend (He sold me the ET2/TNT last year, then he found this Brightstar in his store room recently and send to me separately).

His comment is that with the Brightstar only, its good isolation but the sound is not solid (he describe the sound as floating, I hope you know what it means :P ). He is actually the one suggested me to add a sandbox on the Brightstar and the effect is exactly as he describe to me. He mentioned he did ABC test years ago with only Sandbox, only Brightstar and both.

Working like mine is best (Sandbox on Brightstar), but if only one can be chosen, he prefers the sand box, as this give good isolation and solid soundstage. The choice of sand is also important, we went into lengthy discussion and also based on my experience playing with sand in speaker stand. I choose rather large size quartz sand (each sand is the size of rice), too fine sand actually damp the sound too deadly.

For the Dental Floss, I haven't tried it yet, I need some education on this, how to source and fit. I did compare dual belts and single belt as suggested by some veteran in the VPI forum. And I agree that I like the dual belt setup better, seems to give me more solid bass.

Best Regards
Eric
