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'!

@spiritofmusic The additional 3” dia x 30 cm smoothing tank required ‘increased’ pressure. The original pump was almost maxed out. I switched to a higher output Enhiem pump. 

An additional surge tank idea is no tank at all. Using long run of copper piping coiled like radiators would be a very effective air modulator. The stiffness of copper, or PVC in the case of the smoothing tank, is the key, as was mentioned by @dgarretson
I'm confused by this. Vic formally warns against using higher flow pumps. 180-250 litres/hour is his recommendation. So if using extra tanks necessitates more pressure/higher flow, isn't this contradictory?
The pump that came with the Trans Fi was a Sera Air 275 R plus with output of 4.5 liters / min, or 270 liters / hr. I am assuming that 270 l / hr is max output. Until the smoothing tank was added, the vol dial on the Sera was at 50%, even with the 20 litre and 25 litre surge tanks in the loop. That means It had been operating at 270 / 2 = 135 liters / hr. However, with the PVC smoothing tank in place, I literally had to turn the pump to max, or at 270 liters / hr, and the arm still was a bit unstable, skipping / mistracking at times. That’s when I decided to increase the output, not knowing really Vic’ recommendation.

The Enhiem 400 output is 400 litre / hour. The volume dial is at 70%, so maybe 280 - 300 liters / hour. And yes, I am a bit over Vic’ recommended range. However, before this whole surge tank experiment the arm was running at 135 litres / hour, a bit less than Vic ‘s range.

I suspect that if I were to place a gauge at the arm, it probably is receiving an output within Vic’s range. But with all the air mudulators added to disrupt air flow, the pump has to work harder at the front end. 
So Ledoux, the benefits audibly of adding extra tanks outweighs the theoretical disadvantages of having to run a higher pressure/air flow?

The  benefits are clearly audible, and not subtle. 

I just sent an email to Vic regarding increased pressure, awaiting his answer.....
