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.
No need to hide your transformers!
With powder coated end-bells in Agnew-cream-white and our fancy engraved stainless steel product plates riveted on, with type designation and serial number stamped by hand as a seal of approval following our extensive testing and quality control procedures, our transformers now look as good as they are!
This item is the latest addition to our collection of experimental transducer prototypes. What you see is a multi-layer miniature winding on a custom machined former, entirely made in-house at the Agnew Analog Research & Development Laboratory.
