Base On STUDER 900 Circuit 2 Way Power Supply Bare PCB For Preamplifier/DAC

Introduction:The circuit of this product is based on the Swiss STUDER power circuit.Ultra-low noise fever linear power supply, with excellent wiring and good linear components, the output accuracy is very high, ultra-low ripple, and the actual listening experience is better than most Class A power supplies.

The maximum current of this device is 2.5A. If your device exceeds 2.5A, it will not be able to start. Please pay attention to the use situation. It is only suitable for commonly used preamplifiers and DAC decoders below 2.5A.

Instructions for use:There are 3 voltage adjustment positions on the PCB, namely: H (DC 20V--28V), M (DC 12--18V), L (5--9V).After setting the gear, fine-tune the adjustable resistance on the PCB to reach a precise value.The corresponding resistance of H is 33K, the corresponding resistance of M is 12-18K (the larger the resistance, the higher the voltage, but the lowest voltage will increase), the corresponding resistance of L is 3K3-6K8. You can change the corresponding resistance value according to your actual situation.

These are two independent voltage outputs. If you want to build a +/- voltage output, you can short the two GND points on the middle of the PCB, and then output + voltage from VCC, GND to ground, and VSS output-voltage. ,very simple.

PCB size: 102mm * 118mm.

NOTE: This is the Bare PCB. You need to match all the parts yourself.
