EMT 930 Glass-Plate

Simply one of the BEST upgrades for my EMT 930!
In the past the studio turntables EMT 927 also were delivered for the disc-recording manufactures optional as a measurement studio turntable. This special record player was named EMT 927 D and it was equipped with a glass-plate instead of a plexiglass-plate.
When it was necessary to obtain the best available accuracy for playing a record a plexiglass-plate was not sufficient, even if it was produced very precisely.
The plexiglass-plate was replaced by a glass-plate although the quickstart facility was eliminated.
Compared to the plexiglas-plate the glass-plate has the following advantages:

  • an absolute flat Surface
  • a coupling of the record with the main plate by the rubber surface of the bottom and the top side
  • a reduction of the static loading
  • an improvement of the technical data (rumble signals weighted und unweighted, wow and flutter) by enhancement of the mass
  • an improvement of the feedback unsensitivity
  • a precise stroboscope
  • an improvement of the optical impression
  • an optimum record rendering by avoiding uncontrolled vibrations of the record
  • an improved performance
The glass-plate can be replaced easily and immediately. So you can win at once an improved performance.

MY DIY ULTRASONIC record cleaner

During the past several months I have invested my time exploring cavitation.
I needed a faster way to clean than my multi-step manual wet/vac cleaning process (using my Nitty Gritty).
My hope was to find that I could complete multiple LPs in a single cleaning cycle and greatly speed up my rate of cleaning records.
The results, also in terms of cleaning results, have far exceeded my expectations.
Stay tuned!
