Description

Product Overview:

The Mono Amplifier Ready Board

4 transistor board 200W RMS @
6 transistor board 300W RMS @

8 transistor board 400W RMS @

is a high-quality, powerful amplifier board that is ideal for upgrading your audio system. Featuring the renowned 2SA1943 (NPN) and 2SC5200 (PNP) transistors, this board delivers outstanding audio performance, high efficiency, and low distortion. Its 200W power output makes it suitable for high-demand audio applications, whether in home theater systems, audiophile setups, or other professional audio installations.

This mono amplifier board is designed for audiophiles who want to push the boundaries of their sound system after upgrading from tube amps. It can drive large speakers and subwoofers with ease, offering deep bass, clean mids, and crisp highs, all while maintaining high fidelity and minimal distortion.

Key Features:

  • High Power Output (200W @ 4Ω): Designed for speakers with higher power handling, ideal for driving large speakers, high-power home audio systems, or subwoofers.
  • Premium Transistors (2SA1943 + 2SC5200): These widely used power transistors are known for their reliability, performance, and ability to deliver high-output with minimal distortion.
  • Mono Amplifier Design: This board is built for mono operation, which is ideal for dedicated channel amplification or large, high-power setups (such as a single subwoofer).
  • Post-Tube Amp Upgrade: This board works as an ideal upgrade for tube amplifier systems, providing added power and improved audio clarity without sacrificing the tube amp’s warmth.
  • Low Total Harmonic Distortion (THD): Offers crystal-clear sound reproduction with very low distortion (<0.1%) even at high power output.
  • High Efficiency: Optimized for reduced power consumption and effective heat dissipation for extended listening sessions.
  • Easy Integration: Designed to be user-friendly for both DIY audio enthusiasts and professionals, with accessible connections and mounting points.
