Trans-Fi Terminator Tonearm: 2019 Update

In reading a few related posts on linear tracking tonearm, in general,  and Trans-Fi Terminator , in particular, I thought I would give a brief update of the Terminator.

I purchased the arm directly from Andrey in Moscow two months ago. From what I understand, Andrey has taken over production after Vic's retirement. What I received is the most up-to-date version of the arm with the carbon fibre wand and brass counterweights, the direct wire leads from cartridge to  phono amp, and a new brass manifold ( not evident from the main web-site). Both the wand and the new manifold are Andrey's contribution to the continued refinement of the Terminator.

Also,  please visit this site: https://darklanternforowen.wordpress.com/2017/04/15/terminator-tonearm-new-arm-mount/. This gentlemen from NZ has developed a new arm mount for the Terminator which advanced the arm's sonics even further. It was reading through the the development of this new arm mount that convinced me to order the Terminator after much prior research. I did not purchase the arm mount from NZ as it would not readily fit my Verdier La Platine, instead Andrey made a custom arm mount. It is in essence a two point support mount rather than a single point support rod that is commonly used. 

My previous arm was a SME V of 1990's vintage mounted with a ZYX airy. The Terminator is several notch above the SME V. All the accolades given to the Terminator seem justified. My main point in writing is that the new developments by Andrey, i.e. the carbon fibre wand and the newest brass manifold, seem to improve upon the Terminator even more ( see link above ). This is the news that I wanted to share with existing Terminator owners. I asked Andrey to start a blog on all the new stuff that is happening with the arm, but it seems that he is busy making 'things'!

I've had the transfi tonearm for over 5 years now. Used a Danner AP-8 (Sera/Top Fin). Out of the box it never had > 1.6 PSI all the way up at the pump. But the arm seemed OK around 1 PSI anyway. Only used a 1 liter tank near the pump.

Decided to revisit all this, had a feeling the Danner was never really good enough, not that I needed more PSI, but seemed like it wasn't optimal.

Reading posts about large and multiple smoothing tanks. But that many large tanks seemed like only something like the Hiblow pump could handle. So I tried a 6 gallon tank, using a Fluval Q2. Out of the box this had 4 PSI at the pump. But it could not push any air out of that size tank for some reason, no leaks either. So went to a 2 gallon, then to the 1 liter tank which is now ~ 3 feet from arm. The Fluval was able to push thru those OK, albeit it loses ~.4 PSI by the time it reaches the arm, which is fine. Must be the amount of back pressure these pumps can handle, the Danner seemed weak comparatively.

As others reported, the extra smoothing tank and stronger pump made a very nice difference. I may do a Hiblow someday, and get the 6 gallon tank running. But for now, I wish I would have spent the extra $$$ sooner and did this right.

@dnicol  Very happy that the added surge tank contributed to better SQ.
I am a bit curious as to why your pump cannot work with the 6 gallon tank. For my application, there are four surge tanks / filter connected in series. The surge tanks ( plastic water containers ) are 4 + 20 + 25 litre, so approximately 10.8 gallon in total. The originally supplied Sera pump had no problem pushing through these. And the sound quality improved with the addition of each tank, so I am wondering why the 6-gallon tank won't work?  

I added a fourth filter consisting of a 3" PVC pipe, 40 cm in length capped at both ends. The addition of this PVC filter caused problems for the Sera, whereupon I switch to a Eheim 400 pump which is still in service.

I would encourage the addition of extra surge tanks. I believe you will be able to hear increased improvement.

When I had my Eminent Technology ET2 running on lower pressure similar to the Transfi putting the air pump on an isolating transformer improved the sound quite considerably, even with copious amounts of surge tank capacity in situ.

"I am a bit curious as to why your pump cannot work with the 6 gallon tank."

Let me clear that up a bit, the 6 gallon tank does eventually fill, but it takes 4-5 minutes for it to show max pressure at the outlet with a gauge. So I decided that it seemed to be too much back pressure on these little aquarium pumps. Moving to a pond pump would of course take care of that problem, but there's the overkill aspect as well. Currently a 2 gallon and a 1 liter tank fill much faster, and is likely much easier on the pump, and still provide plenty of reserve. Moving the smaller 1 liter tank very close to the table seemed to help as well.

My take on the sonic effects, is while the smoothing seems beneficial, (vs pulsing, although the Fluval pump pulses much less than Danner types), I wonder if having all that reserve tank air is helping as well, not relying so much on the pump being consistent. The consistency comes from a full large tank itself.

@dover  Could you point me to a recommended transformer?

Also, Here is an update on the wire harness / VTF front. I would spin one side of a record to allow the wire to settle. Then comes the VTF measurement with each listening session.There is usually a 0.03 g VTF variation between inner and outer groove. The biggest variable is  temperature/ humidity. With a recent cold front coming through our region, adjustments had to be made. But otherwise, the VTF has been very stable.
