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'!

Thanks, Terry! Your surge tank foray was the inspiration.

I read recently a Terminator owner in Hong Kong who uses a 50 liter tank with a Hi Blow 20 series pump. And he uses a smaller, 5 liter, tank in series, before connecting to the tonearm. The total volume of his surge tanks is close to what I have, though I feel that breaking the tanks into smaller piece may help in smoothing out the air fluctuation more. 

As VTA / SRA adjustment can be done on the fly, I did a bit more study. I am finding that with almost all records, I am adjusting VTA within a 3.5 - 4 mm range. Given that the pivot to stylus length is approx. 85 mm, the height adjustments translate to a 2 - 2.5 degree angle difference. I am slowly getting a feel for the thickness of the records, and where the optimal VTA should fall for that perfectly dialed in sound. And no two record is dialed in with the same setting which means no two record is cut quite the same. I am of the opinion that there is no magic 92 degree rake angle that very cartridge should be tracking.

Very intriguing! I run a Terminator and also have a surge tank close to the arm, made from 4" PVC pipe capped at both ends.

Can you tell us what you used for your 20 and 25 liter tanks? Where you got them and how you made them?

And also the link to the Hong Kong guy?

The thread is in Chinese, but the response with surge tank info is in English near the top of the thread.

The surge tanks  that I am using are generic plastic water containers. They are similar to  the gallon surge tank supplied by Andrey, just larger. Inlet / outlet holes are drilled and filled with chrome plated nozzles, inlet at bottom, outlet on top. 1/4” silicone tubes are used throughout.

Of the three tanks, I have filled the two larger tanks with a mix of crumbled paper balls and cotton balls, a little less than half full. @terry9 apparently fills his tank with cotton balls to within a few inches near full. 

A final word on VTA. Since my VTA setting ranges within 4 mm, I have made VTF measurements at the high and low VTA settings. The VTF differential between 4mm is around .03 g. My VTF is set at 2.0g in the middle of the VTA range. Moving the VTA up and down 2mm from the middle will result in a change of VTF of max. .015, so pretty negligible.

I've been chatting with Simes about this. My pump is over 55'/15m from the stock smoothing tank, thence 15'/5m to Terminator. He contends that length of air hose will already be doing a lot to smooth air flow, but I'm game to try an extra 30 or 50 litre surge tank, filled with cotton wool or crumpled paper balls to aid smoothing.

What is the specific Google search to use for these tanks and the nozzle attachments required?
