This product has collected a lot of user feedback, after three months of design and debugging, the third generation of the latest version of the LM1036 N + NE5532N tone board officially listed on sale!
Compared with the previous generation, Rectifier part of the original use of the diode, now switch to 3A rectifier bridge. Rectifier bridge in parallel with four 0.1uF monolithic capacitors, the role of the transformer is generated by the high-frequency signal bypass rectifier bridge through the capacitor bypass, thus avoiding the ''modulation AC sound'' and ''modulation rolling cross'' generation.
Positive and negative power supply with two LED lights. The volume potentiometer is placed at the end of the audio output so that the volume control is very uniform.
PCB circuit completely re-wiring, design more reasonable and beautiful. Fully consider the single point of ground wire, no AC interference, high signal to noise ratio.
Operating voltage: 9-15V (Special Note: This board can not be directly used 12v battery or DC power supply, to use the positive and negative dual power supply DC or dedicated AC 12v transformer power supply.)
