Amplification line: This line comes from the "Audio Power Amplifier Design Manual" edited by Dougls, UK. Douglas pointed out in the book that "defect-free" is not absolutely perfect, but refers to the eight known distortions in traditional power amplifier circuits. For correction, the total harmonic distortion measured under a load of 1 kHz and 8 ohm according to the sampling circuit is 0.0005%, and the total harmonic distortion measured under a load of 101 kHz and a conversion rate of 35 is 0.003% . V/us. This production line is adopted by many famous machines, such as new music fax A1 class A power amplifier, Langquan EVO50 and Gentleman.
Output tube: Toshiba's famous UHC-MOS (n-channel ultra-high current FET) K851, parameters: 200V 30A 150W, low output internal resistance as low as 0.085 ohm (control power, bass guarantee), input capacitance: 2100p
Balanced wiring: The power tube of this board has a large output current (30A) and a small output resistance (0.085 ohm). It is strongly recommended that this board maintain balance.
Power supply: AC20-38v recommended to use AC35v, corresponding to 100w / 8 ohm
Output power: 30-120w / 8 ohm
Plate size: 121 * 184.5mm 2mm thick plate, 70um thick copper
Quiescent current: It is recommended to use a current of 50mA to measure the voltage between T1 and T2 of 5 to 10mV.
Buyers note: The product picture includes 4 large capacitors
