Michael Yee’s continued research into power supply designs has resulted in our Linear Power Supply (LPS). Originally designed as a “no holds barred” power supply for charging the battery packs of our flagship Super Nova III phono stage this is a “Classic Analog Power Supply” which uses a 50/60 Hz transformer, large storage capacitors, and low noise linear Voltage Regulators. All of this is in service to achieving the goal of reducing noise for the best possible sound from an Audiophile Turntable System.
When used to power the Phonomena 2, Phonomena 2+, and Nova III phono stages, the LPS will dramatically improve their sound by providing cleaner power and eliminating the noise from a Digital Switching Power Supply. This switching noise is higher in frequency than the audio signals and can modulate the actual audio signal. The Power Supply Voltages may also have the switching noise on them. A Digital Power Supply also radiates via Magnetic Field Emissions that can be transmitted to other components in the Audio System.
The LPS uses a Tamura Transformer to convert the line voltage to a usable voltage for the Musical Surroundings Solid State Preamps. Tamura Transformers are very well known for use in Tube Amplifiers, Tube Power Supplies and other audio circuits.
Large filter capacitors and rectifiers are part of a noise reduction circuit before Ultra Low Noise, Low Dropout, Precision Voltage Regulators (Linear Technologies LT1965, LT3015). A Single Supply Connection (+22.5V) is supplied for Phonomena II, Phonomena II+, and Nova III. A multi-pin Split Supply Connection (+/-11.25V) is supplied for the Super Nova III and future designs.
When used as a power supply upgrade for Phonomena 2+, Nova II, or Nova III:
Connect one side of the power link cable to the linear power supply unit and connect the other end to the power supply input jack on the back of your Phonomena 2+ or Nova II. Then connect the IEC power supply cable to the back of the linear power supply and to your AC mains. Turn on the switch on the back of the linear power supply unit and your phono stage will light up and is ready to use.
When used with SuperNova III:
Use the locking umbilical power cable to conncect the Super Nova III to the large multi-pin connector on the back of the linear power supply, then connect the IEC cable to the back of the linear power supply and to your AC mains. Turn on the switch on the back of the linear power supply unit and your phono stage will light up and is ready to use. Consult the SuperNova III manual for further information.
