( ---☆ ayanhu81 ebay shop welcome you to buy it ☆---)

Note:

This is a DIY Kit,need buyer to assemble it.

STUDER line to the power line modeled output very high precision, low ripple, the actual sense of hearing is better than most Class A power.

Double-sided Immersion Gold PCB, finishing tube 5A Schottky rectifier, NOVER Gold capacitor, the output tube ONMJE15034, adjustable resistance for the BI (picture not has been replaced, the actual is BI), the reference voltage regulator board with a dual op amp TL072

Input voltage range: dual 9V-24V (4 line transformer)

Output: ±DC 5V-28V or dual DC 5V to dual positive 28V with short circuit protection.

The maximum output current 2A.

PCB size: 102 X 118 X 37MM

2 green terminal tail is AC input. For example, you transformer is AC 18-0 18-0

Instructions: ( ---☆ ayanhu81 ebay shop welcome you to buy it ☆---)

Board regulator has three stalls, namely:

H (high) above the output voltage of 20V, maximum 28V, the voltage level circuit for discrete components.

M (middle) output 12-18V, suitable for pre-amp.

L (low voltage) output 5V-9V, power supply for DAC.

Set up stalls after trimming the board of adjustable resistance, it has reached the exact value.

H corresponding resistance is 33K

M is the corresponding resistance 12-18K (the higher the resistance the greater the voltage regulation, but the lowest voltage will be raised)

L corresponding to the resistance is 3K3-6K8

When you use two sets of odd and even independent DC output, such as 1 Group 5V and 1 group 9V, you can output directly from the green terminal.

If you want to set the positive and negative power to the amplifier, it can short-circuit the intermediate pad gilded fly above the line, and then from the VCC output positive, GND to ground,VSS output negative.
