Field Effect Tube (2SK2955, 2SJ554) Power Amplifier Board (Imitation Dragon PMA-S1). Using original MJ15024, MJ15025, 2SK2955, 2SJ554 (removing the machine tube).The main circuit of electrolytic capacitor signal adopts Taiwan, and the main filter capacitor adopts Japanese audio special? Capacitance capacity is 2×6800UF/63V, and domestic 16A and above rectification is adopted to ensure strong and continuous power support. The resistor adopts 5-ring metal resistor, and the main circuit adopts 5-ring metal film resistor with an accuracy of ±1%, which ensures a good signal-to-noise ratio of the whole machine. The PCB adopts 1.6mm thick double-sided plate, 2.0oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents. The power output stage adopts super-current field effect tube 2SK2955, 2SJ554. Due to the low pressure resistance of the pair of tubes, a pair of gold-sealed large tubes MJ15024 and MJ15025 are used to supply power to them by sliding, so that the field tubes work in a constant voltage state and will not break down.
This board adopts the current advanced UPC1237 speaker protection circuit to make your speaker safer. Supply voltage: AC dual 28V-34V, It is recommended to double 34V/400W or more Output power: 150W2 Speaker impedance: 4-8 ohms PCB size: 285105MM.
