Single-ended Class A amplifier
This amplifier is designed with zero negative feedback (ZeroNFB), pure Class-A and definitely single-ended. The amplifier is built around the BUZ-900 N-Channel MOSFET
We use Mundorf Mcap SUPREME SILVER / GOLD or AMPOHM WOUND PRODUCTS – FP-CA-10-AU capacitors
for the input coupling and a large electrolytic on the output with a 10 µF polyester bypass capacitor. The four 20 watt
Mundorf`s amazing M-Resist™ SUPREME or Vishy 30W 1% non-inductive wire-wound resistors act as the load.
This amplifier is powered with stabilized separate power supply, consisting of 300W transformer, 4 ultra fast shottky diodes MBR4060, low drop voltage regulator LM7824 and high quality electrolytic capacitors (Nichicon). The power is filtered using 40000µF capacitors model NICHICON – LLS1H103MELC
