Description: Details：Double-sided gold-plated PCB718 resistance2SC945 A733 precision pairing input transistorON NJE15034/35 push transistorJapan Omron +UPC1237 protection circuit to ensure safe and reliable output, protect the speakerMidpoint servo circuit makes the output more stable without zero adjustmentA60 circuit module, current feedback, the main feature of this circuit is from the input stage to the output pole all adopt complementary push-pull circuit, can easily get hundreds of volts per microsecond conversion rate, drive capacitive load is quite good.Adjust the quiescent current of the large transistor to 100-300mA. There is 1 TEST point on the board. Test the 2-terminal pressure drop to 20-60MV.Parameters：Operating voltage: AC24VX2 ~ AC42VX2 plus AC12V Note: AC12V is used to protect the circuitOutput power: 200W 8Ω / 300W 4ΩDistortion: 0.002%SNR: >100dBOne channel pcb size: 195*80 mmCan provide suitable chassis and transformer ！ Verion 1：Assembled Board：Not included 4pcs main capacitances and 6 pairs power transistorSuitable high power transistor model：MJL3281A MJL1302A / 2SC5200.A1943 / NJW3281/NJW1302Version 2：Assembled Board：included 4pcs nichicon KG 10000Uf 50V capacitances and 6 pairs 2SC5200 2SA1943 power transistor ！
