The CCY Engineering SS300B-25C is a Malaysian-made, high-performance solid-state amplifier that uses a single-ended Class A design to emulate the sonic characteristics of 300B vacuum tubes. It features a MOSFET-based output stage with zero negative feedback, offering 25 watts per channel of "soulful," warm sound. 
 
 
 
Topology: Pure Class-A, Single-Ended Solid State (SS).
Sound Profile: Designed to provide the rich, emotional, and warm sound associated with 300B tube amplifiers but with the stability and power of solid-state MOSFETs.
Power Output: 25 Watts per channel, designed to drive various loudspeakers effectively.
Components: Utilizes high-quality components, including Mundorf or Vishay resistors.
Input Stage: Features ultra-low-noise NJFETs for high signal integrity.
Variants: Includes power amplifier versions (SS300B-25C) and preamplifier versions (SS300B-Pre) with high-bias, discrete components for audiophile, bi-amp, or tri-amp applications.
