Product Details

Product Description: This set is based on the original HA5000 amplifier circuit and needs to be welded by the player. The kit does not contain potentiometers and headphone sockets and needs to be purchased separately. PCB size: 100*100*1.6MM FR4 A grade plate. HV2-SE technology highlights: 1. Miniaturization: reduce the original super-large PCB to the current 10*10CM to suit all types of chassis. 2. Modify the form of double single independent power supply, change it to two channels sharing one cow and one bridge, filter and stabilize voltage power supply respectively, so as to reduce the input cost. 3. Change the original electronic filter mode to the tristable voltage tube type to supply power to the input stage and the voltage amplifier stage, and the ripple coefficient is even lower. 4. Optimize the first stage constant current source, optimize the adjustable single tube JFET constant current source to double loop constant current source, and set the current to 1 1MA per tube, which is consistent with the original machine and reduces the debugging steps. 5. Cancel the coupling capacitor input part attached to the original machine, and retain the pure direct couple input. By comparison, the pure direct couple input has the most direct sound quality and less sound dye. 6. Keep the characteristics of the original machine, use AB carbon film resistor for signal input and feedback. 7. The driving stage is changed to C3421-A1358 with higher current in the same gate. 8. Remove the extremely complex protection circuit, and the player can choose the protection kit independently. Input voltage for recommendation: AC15-0-15, not lower than 30VA. Select R-CORE for recommendation. Debugging: terminal current 100MA. Adjust 1K adjustable resistor so that the TP point voltage is 47MV. Adjust 100R adjustable resistor to infinitely limit the neutral point voltage to OMV. Packaging: 1pc Headset Power Amplifier HV2-Se Class A Full Direct Even Headset Amplifier Kit
