Introduction: M4 originates from a generic circuit of UK Sugden SF60. This circuit is incredible, reproducing music melodies that are infinitely immersive and intoxicating. The pure and natural sound quality is fully implemented in the circuit, especially in the sense of medium and high frequency layering and delicacy. The effect of this power amplifier is much better than those using NEC UPC2581V as the driving transistor. Especially in the mid frequency, it is much more comfortable to listen to, and more importantly, the input operational amplifier can be replaced to achieve the fun of sound matching and upgrading! If the heat dissipation is sufficient, the machine can also be adjusted to pure Class A output! The product comes with complete overcurrent protection, delay protection, and output DC protection to protect the safety of expensive speakers. Input voltage: AC 22Vx2 to 36Vx2 (Recommended to use AC 32V-0-32V) PCB size: 153mm * 128mm Output power: 150W+150W (4 ohms), 100W+100W (8 ohms) Frequency response: 10Hz –40KHz Debugging instructions: M4 debugging is very simple, just test the static current of the output tube, measure the two points of TEST on the PCB, and adjust the voltage to 10mV -40mV
