Eminent Technology ET-2 Tonearm Owners

Well I guess it's time for me to stop lurking and ask some questions. I've enjoyed my ET2 for 25 years or more and rediscovered this thread last night. I  have a SOTA nova table with cosmos armboard made for the ET2. This has metal contact points for the base tripod and works well. I recently upgraded to the aluminum base, joint and VTA display. Running two WISA pumps out of phase and getting 7psi on my pressure gauge, with two diy surge tanks in series, and a small surge tank made from a  plastic gas tank for R/C planes located very close to the arm.
This last tweak hasn't been mentioned here but I think it helps. My I-beam is from the hobby store as well (twice the usual length) and allows me to place very little weight way out the beam. (There are limits I discovered.) My manifold is the high pressure one, tried with a shop vac and pressure regulator up to 30 psi, but the quieter background wasn't worth the noise in the basement. So, I'm back to the WISA's now. My cartridge is the Lyra Kleos recently replacing a still functioning 20 y/o Audioquest 7000 NSX. Arm is the magnesium one.
I've learned a lot in catching up on this thread and really appreciate the dedication and enthusiasm of this group for the ET-2. -I thought I was the last fanatic out there.
My plan is to try the double and/or triple leaf springs, maybe go for the Alita pump and start using the regulator again. 
I would also like to try the direct wiring harness, but don't know where to look for one. Any links available?
Thanks for a great discussion and cheers,
John

Hi, John,
Welcome aboard.  You are definitely at the right place.  Like you I've owned my ET II for over 25 years.  It's hard to beat.  The guys on this thread have vast experience with our arm and are quick to give great advice that really works.  No snake oil here.   I think, however, they are ready to throw me off this thread.   I can't believe that after 40 years as a wanna-be audiophile I was so stupid as to have my VTA so far off.  (See my last post.)  I'm really embarrassed 😡

Don't know if Chris will ever forgive me.
Cheers,
Harry

Hey Harry,
I found that it's easiest to set VTA with the Lyra cartridges by starting with the top of the cartridge parallel to the record surface and wiggle up and down from there by ear. -The little gauge that Bruce sells helps with very small adjustments and only $80.
Did you ever deal with Taylor House up in NC? 
Regards and thanks for reading my post,
John

Thanks for the VTA tip John.  I'll have to look into Bruce's gauge.  Is this his set-up gauge or one just for VTA?   No, I don't recall having dealt with Taylor house.  Where are they?

There's a picture of the VTA gauge on the ET site. Go there-products-ET2.5-VTA gauge.
Taylor House is in Sherrils Ford outside of Charlotte. I think Robert is still in business, but haven't called him in a while. I bought most of my analog gear from him.
