1. Board overall nice, reasonable layout, with the blue and yellow chemical capacitor large radiator, very beautiful
2. Green Oxidation large radiator, good heat dissipation
3. High-frequency low-impedance capacitors, stable and reliable performance, output distortion is smaller, powerful bass, midrange and treble clarity, sound sweet


Caution:
1 Rated power supply voltage for dual ± 50V, the voltage at ± 42 --- ± 58V can work, because this amp has undervoltage and overvoltage protection, it is recommended not to lead nearly voltage supply voltage protection point, because if the power at high power voltage fluctuations, if the voltage is lower or higher than the scope of protection of the moment, was closed to protect the amplifier output, while the staccato, do not reverse the positive and negative power supply
2 power supply is recommended to ± 50V DC dual power supply filtering better
3 speakers recommended 6-10 inch 4 ohm or 8 ohm trumpet
4 Although the audio output short circuit protection, but try not to short-circuit
5 Check carefully before energized, make sure the wiring is correct before pass.
6 This panel voltage is fixed at 36 times magnification, if the output power is not enough, as the case may add their own pre-amplification
