We recently had the pleasure of having Symatic over, from Bristol, UK, for a week of training on how to cut (and how not to cut) records.
Symatic runs Cut & Paste Records, a record label attracting some serious attention among skratchers, with high quality releases of skipless skratch samples, lock-groove tones, beats, and relevant music.
A customer recently imported a vintage Presto 75A disk recording lathe from the USA, with a view to cutting records in Europe.
He quickly discovered, like many people before him, that it was spinning a bit slower than it should, when operated from 50 Hz mains, via a simple step-down transformer. As with most vintage record cutting machines, the platter is powered by a synchronous AC motor, which "locks" to the line frequency.
It started life in the 1940's as a completely manual machine. A sturdy design, capable of very decent results, these lathes were extensively used across the USA and other parts of the world for several decades. Many are still in operation today. In the original condition, they were quite limited in what they could do. But, as with most good lathes, they can take a lot of modification and improvement.
Meet George Vardis, a retired biologist with a Master's Degree in Food Technology, residing in Athens, Greece. George is a sophisticated man with many interests, including sailing, photography, motorbikes, and music. He plays the piano and the guitar, but his career always steered well clear of the music industry. He was never a recording artist, nor was he a recording engineer. In fact, he has probably never seen a recording studio in real life.
The AM44 is a Neumann-based lathe, built on original Neumann castings, manufactured around 1944, during the second world war.
The project was founded by Flo Kaufmann, in Switzerland, when he managed to find a pile of these rare beds in the unexplored depth of a warehouse. The plan is to build them up into fully functional disk mastering systems, using newly designed and manufactured parts.
John Delias, the guitar wizard of the popular rock group "Naxatras", filmed J. I. Agnew while cutting the master lacquer disks, from which the vinyl records of their debut LP were manufactured, at Magnetic Fidelity, and edited the footage to produce this short informative video, offering an insight into this seldom seen, mysterious process.
One might think that the whole issue of absolute polarity for a medium essentially invented around 130 years ago, would have been adequately discussed and standardised by now, leaving no room for further debates. Indeed, it has been, so why bother writing anything further on this topic?
