Description

Summary:
HP-2 Super Parallel regulator CPI servo power, low internal resistance, high precision, excellent transient response,
ideal for sanding DAC, preamp, amplifier voltage amplifier stage and the input stage, actually listen rich sense of
low-frequency, high frequency and delicate.

PCB Size: 75mm*125mm*50mm

The main capacitance is two original Nichicon KG Type I 10000uF/50V.

NOTE: This is a Kit, All parts need you to weld and test.

Highlights:

1,  use  double bridge rectifier, in the dual single  systems can use one transformer

2, low noise <350UV, high voltage stability after thermal stability over / load regulation of <0.5%, followed by basic non-load voltage drop

3, the voltage adjustable upon request from 8V-50V. Current output 10MA-1.5A (depending on the rectifier with the regulator varies)


       Output voltage and the input voltage (DC) recommends no less than 4V pressure, recommended 5-8V pressure, low pressure
will affect the stability of the filter lines and voltage, the effect dropped.

A reasonable set of input current, generally set higher than the amp quiescent current 30% , too high will make the sound get
stiff, high voltage and high current, note the adjustment tube heat problem.

1, R1

      Output current = 0.65V / R1,   R1 = 10R . on the board has two Reserve position for R1, generally for the preamplifier or voltage
amplifier stage, R1 use 10R will be ok, to play a little more extreme,you can According to the above formula, you can by adjust the
single or dual resistor to Get personal preference sound.


2, R2

Output voltage is 12-30V, use about 10K

Output voltage is 30-50V, use about 15K

Output voltage is 50-60V, use about 22K

3, R3

Output voltage is 12-30V, use 4K-5K,

Output voltage is 30-50V, use 11K-12K

Output voltage is 50-60V,use 12-16K

Note: the Default finished board R2 R3 Resistor is for Less than 30V output voltage.
Standard Edition uses ST BD139-140 as  regulator, if you need voltage output more than 50V, need change the BD139-140 with A1358-C3421.
and the also need change all the caps voltage more than 50V, But you need to have their associated parts.
