Field Effect Tube 2SK2955 2SJ554 Power Amplifier Board (Imitation Dragon PMA-S1)
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. This item is in the category "Consumer Electronics\TV, Video & Home Audio\Home Audio\Receivers & Amplifiers\Amplifiers & Preamps". The seller is "laserworld2014" and is located in this country: CN. This item can be shipped worldwide.
