Komuro Amplifier Company K300S Stereo Amplifier

Only ten of these amplifiers will be built.

  • 52 pounds
  • 17 x 12 x 9 inches (WxDxH) including tubes
  • Tube compliment: 6BM8 (x2) 300B (x2) 274B (x1)
  • 7 Watts per channel pure class A *

Unique chassis materials and construction keeps the tubes and circuit isolated from the seven transformers and chokes, preventing vibration from effecting the musical signal.

Additionally, the fully custom C-core power and output transformers are shielded and potted for minimum resonance, vibration, and interference.


* Output transformers are not multi-tapped for different impedances. They are designed to use the entire secondary for the output and can be configured for 16, 8, or 4 upon order. This configuration can be changed at the factory in the future.
