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.
