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'!

Re the isolation transformer.
So i have to be careful because how the power is delivered varies by country. In new Zealand we have 230V and separate phase, neutral AND ground.
An isloation transformer is simply a 1 to 1 transformer - 230v in and out.

From wiki...

An isolation transformer is a transformer used to transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source, usually for safety reasons. Isolation transformers provide galvanic isolation; no conductive path is present between source and load. This isolation is used to protect against electric shock, to suppress electrical noise in sensitive devices, or to transfer power between two circuits which must not be connected. A transformer sold for isolation is often built with special insulation between primary and secondary, and is specified to withstand a high voltage between windings.

Isolation transformers block transmission of the DC component in signals from one circuit to the other, but allow AC components in signals to pass. Transformers that have a ratio of 1 to 1 between the primary and secondary windings are often used to protect secondary circuits and individuals from electrical shocks between energized conductors and earth ground. Suitably designed isolation transformers block interference caused by ground loops. Isolation transformers with electrostatic shields are used for power supplies for sensitive equipment such as computers, medical devices, or laboratory instruments.

These days most people use RCD's ( fast acting circuit breakers ).
I did not use an audiphile device, just an old school large isolation trans as described. An electrician should be able to point you in the right direction for your country/environment.

Great news on the VTF variation - 0.03g sounds pretty good.

@ledoux1238,

Reading your posts about the VTF changing due to the wire.

I use Cardas 34x4 "Clear" Tonearm Cable. Very very light and flexible. I haven't noticed VTF change due to the little wire holder clip on the manifold using this cable. The cable I got from Vic, the stiffer litz that you could literally spread out the strands and it would stay, now that sort of wire might cause some changes, or even other types, but the Cardas is literally almost like a wet noodle.

It seems that finding the "optimal" PSI or pressure for the manifold is not that simple.

Adjusting pressure down until it skips or mistracks, then adding pressure until it's gone, may not be exactly optimal, since adding even more pressure than this test calls for changes the sound and the soundstage, and even bass response, IME.

Certainly if you hear air noise when setting stylus in a stationary groove would be too much pressure.

You also can't throw out a number like .3 or 1 PSI, because the weight of the cartridge, mounting parts, brass weights on pivot points, aluminum or carbon wand, will change the amount of PSI needed.

Adjusting by ear for now.

How do others do this?

@dover Thanks for the explanation on transformer. I'll consult a local electrician. It's 110v here.

@dnicol  Regarding wire harness, I am using a XLR set of wires sent from Andrey. Coming out of the cartridge, it is split into four feather thin wires, two per side of wand. They are co-joined at the pivot point.   Would you mind sending me an photo of the way you dress your wire. al dot ho at hohou dot com.I really would like to see how it is done right.

Regarding pressure on the arm, I am adjusting by ear.I have yet to install a pressure gauge.
