Now you can use any Garrard 301 or 401 turntable with any voltage 120 or 240V and with any Pulley Wheel 50 or 60 Hz.
This Power Supply works with any Garrard 301 or 401
And for example UK version Garrad 301 240Volt 50Hz sounds better(motor run smoother and quieter)
than Garrard 301 US version 120V.
With this PSU you can use UK Garrard 301/401 in U.S.A. (with main 120V 60Hz)
UK producer describe:
This very versatile unit is a pleasure to use and makes a 301 and 401 reach its potential.
The unit allows the user to lower the line input voltage going to the turntable down a level where no vibration can be heard from the motor. Surprisingly the Garrard motors RPM can still be maintained on a lower voltage . Best results are obtained with the Eddy brake magnet out of the way of the disc or even removed as with this PSU its not required anymore as all speed selections and alterations are done by the PSU controls.
So by lowering the line voltage right down and making fine adjustments with the HZ control it is possible to tweak the motor to just perfect performance and the net result is consistent speed stability and virtually non existent mechanical noise .
You can forgot about any spindle 50 or 60 Hz, PSU can control any Garrard 301/401 50 or 60 Hz made.
A smooth consistent sine wave makes the motor run smoother and quieter
These units have dual voltage UK and USA 240/110 selection is done with a voltage selection switch.
The sine wave above can be brought together (more HZ cycles per second) up to 80 HZ by using the center control of the PSU to the right clockwise .Or the sine wave can be widened (less cycles per second ) by turning the control anti clockwise which will go down to around 35 HZ cycles per second
