The Secret Society of Lathe Trolls

trans2.JPG These transformers can be used to match a cutter head of unusual impedance (usually too high) to a normal amplifier (usually 8 ohm) or a cutter head specified at 8 ohm to an odd amplifier (500 ohm or anything you like). They are made to order, for a specific impedance match. For example:...

The consistent standard of "positive pressure = stylus moving to record edge" goes back to the ancient mechanical recording and playback method: All mechanical recording lathes and gramophones cannot but work this way due to the simple horn+diaphragm+lever+stylus assembly. Any gramophone soundbox (...

It is possible to mount on many older lathes, we can supply custom brackets for the Caruso head, for different lathes.

Thank you, Patrick. I also love the aesthetics of the Fairchild machines.
Funnily, grandpa Fairchild meets the grandchildren: Some of the modern components are made by Fairchild Semiconductor!

If you cannot find the original part anywhere, I can make you one. Don't worry about it, we can certainly get you up and running again. Let me know how it is going.

Handcut, thank you! We will try to keep on posting on a regular basis. We are also still adding a lot of content to the website. Gridlock, they can indeed sound good if in good condition. Fortunately, they are quite simple to rebuilt if needed, several people on here do such work on magnetic heads, ...

cuttingsystem.jpeg I am selling my Fairchild lathe project as I really need lab space for further work on AM44 development! I really love this lathe, it is a rare piece of precision engineering and one would be hard pressed to find other lathes reaching such high levels of performance even in much ...

xfhyjxfgjcgh.jpg Have you ever wondered to what extent the recording equipment influences the sound of a recording? Back in the beginning of 2016, we conducted an interesting experiment at Magnetic Fidelity, to answer exactly this question, by using an extreme contrast in equipment. We were having ...

I assume you need masters cut and not just one-off records?

If it is masters you're looking for, I would be up for this interesting project.

Please PM me or email at info@magneticfidelity.com.
We are located in Europe.

Normally, the pressing plant should be able to work with unformed stampers that they would form at their end to fit their press. These stampers would be created by the plating facility in Europe from their mothers, but they would not center them or form them. This is fairly straightforward and reaso...

Thank you for the kind and encouraging post, Patrick. Regarding my previous post, I received a lot of emails asking the same questions, so I should offer a clarification here to avoid any misinterpretation of my post: The AM44 is not in production yet. It is still in development. At the moment, the ...

Hello JJG, It is a combination of solid beech wood and beech plywood. The lid can be screwed shut, there is enough room on the corner pieces for that, and I usually tape it up as well. I do not personally use a cardboard box. To protect the appearance of the wood it could be placed inside a cardboar...

Here's a video, produced by one of our customers at Magnetic Fidelity, showing a brief overview of the process of cutting masters directly from tape, using the AM44, fitted with a Caruso cutter head, driven by modified/optimised Caruso preamp boards (my own work), Magnetovolt high-end cutting amplif...

Back in 2016 we developed a super-sturdy wooden shipping box for sending master lacquer disks to plating/pressing facilities around the world. These are not single-use boxes, they are built to last and can be used again and again for years, for a more eco-friendly approach. Designed and built to wit...

Daniel, all standards are in agreement regarding polarity, fortunately. Having said that, standards need to be updated or at last reaffirmed at intervals not exceeding ten years, in order to remain valid. As such, I find it inexcusable that organisations such as the IEC, JSA, DIN, and BSI allow them...

The remaining styli are now on Ebay:

Thank you for your interest. The screenings were very well attended. We did not actually make the film. It was a project by Elina Verykiou. We were asked to allow them access to our facility to film some sessions and did some interviews. We have been told that it will eventually appear online when t...

Yes, correct! Thanks!

Hello Jay, I can supply a complete, turnkey AM44 system for professional mastering work. I also have a few other lathes I could offer, either complete systems or partial, depending on your requirements. In addition, I can optionally offer training on the use and maintenance of professional disk mast...

Apologies to those of you who were told that these styli are no longer available, we had a fellow lathetroll agreeing to buy them all, but not going through in the end, without any explanations.

These are now available again.

Offers will be considered if purchasing all of them.
