This board for the pursuit of clear, pure tone, special use of high-frequency transistor circuit design, the transistor that clear and delicate tone to the end, promote the use of 2 pairs of Japanese Toshiba's audio special pairs of tubes A1943 / C5200 pairs of tubes.
Input using the famous IC as a power output stage using 10 pairs of Japanese Toshiba's audio special pairs of tubes A1943/C5200 parallel output of this board with the real original imported pairs of tubes, or not high voltage and ensure the effect!
This amplifier board has low distortion, low noise, high voltage and switching mute, with perfect over-voltage protection, over-temperature protection, overload protection. The sound color is pure and bright, the component material is no comparison with the theory. Circuit design is perfect. Extremely high sex-to-noise ratio, close to the speaker is also very difficult to hear the noise!
