An essential part of any good sounding headphone or pre-amplifier is a high quality power supply. Do you need a power supply for your headphone or pre-amplifier? We offer several low and high voltage power supply kits. Why not let our modules be the building blocks for your ideas? Of course all of them possess the very high quality components and designs you have grown to expect from Augustica Technologies.
Janus® (User Manual) is a high end DIY dual polarity power supply that delivers voltages from +/-1.25 VDC to +/- 30.0 VDC. Janus® is designed for the highest quality music reproduction with the minimum of distortion. Janus® power supply, with a fixed voltage of +/- 12.0 VDC, is incorporated in our Brig® headphone amplifier. The power supply built from this kit is also capable of driving a wide range of electronic projects which require dual polarity DC voltage. Janus® power supply uses only the finest audiophile quality components that have been carefully selected with no expense spared. Military grade Vishay/Dale metal film resistors used throughout. High quality WIMA and Nichicon capacitors are used along with LM317 and LM337 voltage regulators to stabilize and filter DC voltage. Janus® power supply employs a very generous amount of post and pre regulation smoothing capacitance provided by WIMA and Nichicon capacitors for the total amount of 12,000 microfarads.
Janus® power supply kit is designed for use with transformers that have two secondary windings and a centre tap and AC output of each winding between 24 and 26 Volt AC (for example 182H9 and 182L12).
Janus® dual polarity power supply is shipped the same business day it is purchased via Canada Post Express with a tracking number.
Janus® is also available as assembled, tested and operating power supply. Contact us if you wish us assemble Janus® for you.
