Description
One of the most important upgrade for the new Technics SL-1200 GAE/G/GR series.
Several reviews reported a “shadowy” image on listening to the new series of Technics turntables: due to mass economy and worldwide voltage differences Technics adopted a SMPS (Switching Mode Power Supply) where the switching frequency is at higher end of audible spectrum. Our new MOSFET power supply finally eradicates this problem and gives all the performances that this stunning turntables deserve.
We have also reported by our customers that original switching power supply induces a very audible noise, especially when you run it with a hi-gain or tube pre-phono: our EPS is the definitive solutions for this hassle.
For this reason Technics itself introduced the second generation Gr turntable that uses an “upgraded” power supply, even if it’s still a switching one.
Technics confirmed that the previous PSU introduced noise and they will introduce the new power supply to other turntables models in the future.
As the Gr share the same power supply with G and GAE series it is clear that the original powerr supply is not at the same level of the turntable construction.
Our state-of-the-art power supply is equipped with ultrafast rectifiers provide to feed the turntable with constant DC voltage with very low ripple and a dramatic improvement in audio performance. Generously oversized toroidal transformer (mounted in the external case), Panasonic FC audio grade capacitors, 1% tolerance metal film resistors and selected and matched components with thight tolerances make it one of the best external power supplies that allow the 1200 to express its huge potential.
Our custom PCB is a heavy-duty double layer 2oz high quality fiber with ground plane to provides a low impedance ground reference, shields against interference and allows to fit in the original PCB holder of the turntable.
Completely discrete design, no IC’s to allows superior performance.
Voltage calibration is made by military grade components, not via a cheap trimmer as in other product poorly designed and not intended for Technics turntables from origin.
NO SOLDERING REQUIRED! Just use the supplied screwdriver.
The change is fully reversible and does NOT require any invasive modifications to the layout of the circuits such as traces cuts or external jumpers.
Aesthetics remains the same as our kit use original connections and screws.
Upgraded version with hi-grade power connectors with gold contacts and braided sheath covered cable.
Opposite to other cheap external PSU our kit maintain regulation board inside the turntable to allow quick regulation change, and we do not use cheap design based on LM317 or similar poor regulation board.
External unit have a massive 10mm thick aluminum front panel, clear anodized to perfectly match the look of your SL-1200GAE/G.
With our EPS power supply the deck will maintain all the original functions as strobe light, 33/45rpm switch and pitch control adjust.
