Description

  • Function:

    This is a kit that requires you to solder yourself.

    The kit's complete preamplifier and power circuit
          (excluding phono power and phono sections)


    The focus is on precision film capacitor power supplies. Film capacitors' precision regulated power supplies have allowed the Shizui brand to stand on the market for 30 years. The kit's complete preamplifier and power circuit. This post does not sell amp power and amp parts.




    The power supply maintains the integrity of the original circuit and is compatible with tube rectification. You can switch dual voltages between transistor and tube rectification at will. By default, a single voltage can only be rectified by a transistor, and gallstone hybrid rectification can be simply wired. It is designed to use small 7-pin and large 8-pin rectifiers. By default, the 7-pin socket is shipped from the factory.


    Can use 6X4 / EZ90 / 5AR_ / 5R_ / 5U_ / 5Y _ / ...


    The high voltage part defaults to 330v output, the default setting is 330v310v290v270v gear adjustable output, and the filament low voltage is 3v to 13v continuously adjustable output of LM317.


    This power supply can replace any bile preamp power supply. This voltage requires replacing the Zener diode of the sampling voltage. What voltage is required, please pay attention to the product.

    Screw hole distance of main amplifier board 90x115m'm
