The Avondale MiniCap 6 power supply had been originally
developed for NAP110/140 owners, since its original introduction
the MiniCap 6 has become an extremely popular choice among
DIY audiophiles for power supplies in a large variety of applications.
Most power supplies sections in Hifi amps and external supplies
will consist of nothing more, after a transformer, of a cheap bridge
rectifier and a pair of large, inexpensive reservoir capacitors.
This solution, while adaquate for basic operation, will generally
deliver a slower, less musically reactive sound than can be
attained with some added care and attention to the design.
Considering that the power supply feeds all of the delicate sections
in the amplifier circuit, aswell as the large output devices - stable
power supply rails, even under heavy transient swings, are required
for clear sound reproduction.
We have taken the extra steps above the standard design to use a
CLCLC (capacitor - inductor - capacitor - inductor - capacitor)
circuit arrangement. Using a bank of smaller capacitors, split
using inductors rather than two large units greatly improves the
speed of the amplifier, moreover noise levels are reduced as the
charging times have been cut. In addition we have also selected
ultra fast, high current, rectification diodes as standard to futher
increase the signal to noise ratio.
Using this improved design, as well as utilizing cherry picked
components for high performance and ease of installation we are
proud to offer you the Avondale Minicap 6 power supply. A few of
the immediate upgrades in the layout and materials are:
· High quality PCB with extra large, high current tracks
· Six Kendeil Audio grade electrolytic capacitors
· Proven, rapid CLCLC circuit with high current inductors
· Built in LED ballast resistor
· Individual, ultra fast recovery rectification diodes
· Easy, no soldering, push on connectors
