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'!

Regarding the Fozgometer: I found it useful with the ET arm as it’s nearly impossible get repeatable and dead on  settings because of the nature of the arm. With my Funk Firm or Vpi arms, I just set by ear.

If I remember correctly, the Fozgometer helps to equalize channel separation. This is helpful on cartridges which do have equal channel separation, but not on higher end cartridges which might be quite different. Peter of SoundSmith writes about this, and points out that it is better to have 40dB on the left and 45 on the right than 35 and 35.

Since the Fozgometer helps to set for equal channel separation, you can seriously mis-align a higher end cartridge. At least, I did.

Bottom line is that I would not assume that the Fozgometer will give you a better azimuth setting than your ears.

My procedure is to start dead level, with three screw threads visible on each side of the wand. Then play a record which distorts badly in one channel. Reduce this distortion to almost nothing by adjusting azimuth. Play a record which distorts on the other channel. Adjust as above. Repeat.

It helps to adjust by using only the screw nearest the spindle, as this is most accessible, and it's harder to get confused. Once you've done this, you have a very fine level of adjustment which is stable and repeatable, and amenable to really fine adjustments when you get around to it. I get about 2 minutes of arc.

Good luck!

@ledoux, my air bearing TT is DIY. New Way thrust bushing, custom spindle, 45kg platter.

A Fozgometer is a passive measuring device. When paired with an appropriate test LP and on the correct tracks, the device can take the measurements of the left and right channel output of the cartridge. With the read out, one adjust the azimuth accordingly. If Ledermann of SoundSmith recommends that his cartridge be used with a 5db left / right differential, then a Fozgometer is a much. I certainly don’t know what a 5db differential sounds like. And I couldn’t find info on why SoundSmith’s cartridges would sound best that way. Weird Science? Might need to be enlightened.

@terry9 Thanks for explaining your azimuth adjustment procedure. Adjusting the pivot on the spindle side makes a lot of sense. Do you do it with the wand in-situ? You must be a watchmaker! But then again, you measure your pump pressure to within 20 mm Mercury, way ahead of the game than me. Kudos!

Sorry Ledoux, I seem to have misled you about the Fozgometer. Ledermann suggests that matching L and R output may not be appropriate for all cartridges. This mirrors my experience. That's all.

Yes, wand in situ. No watchmaker, but I abstain from caffeine and alcohol for a few days before attempting a setup. It's easy to measure pump pressure with a sphygmomanometer, used to measure blood pressure. I use a Fairchild precision regulator and set to within 2 mm Hg. Nothing to it.
