History

David’s design concept was inspired by old clocks and watches from the 17th and 18th century. David had often asked this question many times over, why put something of engineering elegance into a black case or even worst, into a wooden case, that looked as if it had been made down in somebody’s garden shed. In fact Transcriptors started the trend to expose all the components so that they could be viewed from all angles. Manufactured from aluminum and acrylic to very high tolerances, tested, the end result always being a highly polished, highly accurate turntable. Designed and built with the skill of an 18th century clock maker, the turntables made for a very satisfying sight indeed.

  1. Hi

    My Player cant hold the Speeds: 33 or 45rpm its just runds out of kontrol.

    What can i Do ?

    • Is it running too slow or too fast? you can try to adjust it with fluid adjustment control. Maybe you don’t have silicon fluid, maybe belt is gone, maybe reservoir fell off.
      First take off platter and see what’s wrong with it mechanically. If you have something wrong with motor, then http://www.transcriptors.net and contact Michael Gammon.

  3. Hi, have the Transcriptor Hydraulic Reference, but my plinth are a mix of wood and acrylic, not Solid polished acrylic as stated in the Specification? does anybody know why?
    Thanks in advance.

  4. Thanks for reply, another question: could I use a speed box, for example the Pro-ject speed box, instead of the oil well, I guess this well are sensitive to temperature.
    gls

    • Hello, no you can’t use speed box as Transcriptors use Single-phase AC synchronous,24 Pole, recoil start motor and Project use DC motor i think. It’s very easy to change speed from 33 to 45, so there’s no need for speed box. Transcriptors isn’t really sensitive to temperature, once you adjust speed. I suggest to buy new silicone oil should old one is dirty and honey-like colored. Please mind that any change in construction will destroy it’s original value.

  5. I just picked up Transcriptors Hydraulic Reference like the one pictured above but it’s missing is power supply where can I purchase one?
