The Sound Carrier Universal Turntable Power Supply represents the ideal companion to your Garrard 301, Garrard 401, Swiss Thorens TD124, Swiss Lenco L75 using single phase ac type induction motors. The UTPS regulated power supply offers fine tuning of turntable speed through both voltage and frequency trim capabilities resulting in accurate 33/45/78 RPM playback, without having to rely on the constantly fluctuating and inconsistent incoming household ac mains power. Greater platter rotational speed stability means improved focus, clarity and solidity during LP playback. Power supply as shown rated for 80W. Ordering instructions, UTPS model options and lead times, please contact Christopher Thornton directly at [email protected]
Black or Silver chassis finishes available.
Sound Carrier Universal Turntable Power Supply delivers
controlled, stabilized and adjustable power to synchronous turntable
motors. Speed is frequency controlled and fine adjustments are possible
to any speed. The input circuit is a rectifier consisting of a
transformer, diodes in a Graetz circuit and an integrated voltage
stabilizer. This is followed by an oscillator with 40-200Hz frequency
regulation to adjust RPM. The signal from the oscillator is pure,
un-distorted and free of power noise. Then a transformer increases the
voltage to the proper value needed to drive the motor. This power supply
is dedicated to lovers of vintage turntables preferably from Lenco and
Garrard but it can drive any synchronous motor. Speed is selectable at
33 1/3 RPM, 45 RPM and 78 RPM and can be fine-tuned. Output voltage is
regulated from 180-230V for lowering unwanted motor vibrations and is
confirmed by the plate-mounted analogue voltmeter. 115 or 230 V input
voltage is set on the internal PCB.
