Eminent Technology ET-2 Tonearm Owners

What an extraordinary hobby this is. RK and I share this wonderful aluminum ET2 Gooseneck that he made - I really like it.

At this current (snapshot) in time however;

RK’s tonearm objective is adding more control and damping to his Krebs Arm.

I meanwhile am trying to figure out how to go wireless with my ET 2.5.

Think Free Willy !

Maybe my IT background biases are showing. With that the damping fluid should be coming early next week with the adhesive tape. Look forward to trying it again after all these years.

Welcome to the thread Spock15. Listing what your air bearing and pivot arms are would be nice to those of us reading for reference.

Thekong has provided some excellent perspective between the Rockport and ET2.

Hi TheKong – were you able to find the lead to make the counterweights at those tire shops ?

Look forward to Rugyboogie providing perspective with the Kuzma Airline and ET2 soon – Congrats on getting an ET2 - RB.

Now we need a Swedish fellow or gal :^) to come on here to help provide perspective on the Air Tangent and ET2. Maybe I will look for one (Air Tangent) to close this loop. However no remote control version for me.

As I type this Ottawa to Toronto area of Ontario experienced a 4.8 earthquake – a little shakey.

Sort of like my JMW 12 unipivot. :^)

One is usually coloured/informed by past experience. Coincidentally, I have a couple of FR64S's myself & you reminded me of the Hadcock GH228 that I have gathering dust.

Another recent unipivot, an Apparition 12" superseded the above. A very fine performer, to the extent that I have had little compunction to A/B with the older arms. A very top shelf pivoted tonearm in my humble experience.

Nothing is perfect in this game (audio & life in general ;)) but with my linear tracker (a Trans Fi terminator) I find the combined qualities of genuine low distortion, wide bandwidth, dynamic stability...are overall most persuasive. Are these attributes typical of linear trackers? I can't be sure at this point.

Regarding Effective Mass...with record groove modulations cut at 45deg, as we know, I think it's not entirely useful I think to dwell on Effective Mass in terms of horiz & vert properties.
Cheers.

I do wish you would stop repeating your fundamental error ad nauseum.
BT measured a rise in response of 6-12 db at the resonant frequency. Say 3 to 8 hz. I don't call these frequencies bass.
Bruce measurements show that this rise in response is reduced by 8db with the addition of an oil trough. This in test conditions which used a deliberately high Q and a low compliance cart. The amplitude of resonance decreases the further you move away from Fr. BT suggests that resonance effects frequencies up to 3xFr.
My rigs Fr is just above 5hz, almost 4 times lower than what is normally accepted to be the lower bass, 20hz.

There is no rise in bass response in my system.

This is the story of an audiophile called Dorothy and her ET2, a tonearm she has owned for many years.

For the first few years she used a light MM cartridge and used only 2 of the 4 lead weights supplied positioned in the middle of the I beam. “It looks visually balanced better this way to me”, Dorothy said. She did have a quick skim through the ET2 manual but ....oh!..... so many pages ....some really technical “guy” must have written that for sure she thought. Anyway.....how she set it up sounded good to her... so she left it this way for a few years.

Then one day she decided to buy an MC cartridge. She noticed it was quite a bit heavier. Instead of moving the existing weight further out on the ET2 I Beam (as the ET2 manual says to do) - she put on the other two weights she had stored in her drawer all this time; so they could meet up around the middle of the I-beam again. She was after all comfortable with this middle of the I Beam positioning. “It just looks visually better balanced this way” Dorothy said. It sounded good again. She was happy.

Then later on she was reading on the internet about some ET2 owners who just couldn’t stop fiddling with their ET2’s.

"Must be all guys for sure” Dorothy thought to herself.

But she was intrigued about how they were discussing the aspect of loading up the weight on the I-Beam. They were putting more thought into it; putting just enough weight on so that the weight was at the end of the Ibeam – no matter what cartridge. Some of these guys were even crazy enough to change cartridge screw sizes to accomplish this.

“Well” she thought to herself “maybe there was a screw loose somewhere else with some of them?”

But she was intrigued ....she could resist no longer. She tried it and did what was required to get the weight out at the end of that “pirate plank” even though it did just did not look right to her.

Lo and behold more music “sprang” forward ! She said to herself “all these years I was listening to my ET2 and I was loving it; But now... well I love my ET2 even more!”

She felt good about herself.
Does this story have a lesson ?

Yes, Dorothy felt good about herself, but it wasn’t because her favorite songs sounded even better to her.... which they did; no, it wasn’t the main reason. You see Dorothy always knew that she could listen to her favorite songs anywhere; even in the car and they would always put a smile on her face. It was about the music itself after all.

No, what made her feel real good – was that she had learned something and understood more about how her ET2 actually worked. That learning and knowledge is what made her really feel good. She then said to herself “maybe I should read the ET2 manual that guy called Bruce wrote? ”

Right after thinking that another thought came into her head. “If only my boyfriend was as easy to tune as this ET2”
