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'!

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.

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.
