PMA-S1 150W+150W 8ohm J15024 MJ15025 2SK2955 SJ554 Amplifier Board YJ

Description:
- Using original MJ15024, MJ15025, 2SK2955, 2SJ554 (disassemble pipe).
- electrolytic capacitor signal main circuit adopts famous brand in Taiwan, the main filter capacitor used in Japan Chemical audio-specific capacitance 2 × 6800UF/63V, using domestic rectifier 16A and above, to ensure strong support for a steady stream of power.
- Resistance selection Rings metal resistance, the main circuit employs a precision of ± 1% metal film resistors rings, ensure the machine a good signal to noise ratio.
- PCB using double-sided sheet 1.6mm thick, 2.0 oz copper thickness, HASL whole process to ensure that the size of the current through the good performance. First-class quality of the PCB.
- power output stage with large current field on the tube 2SK2955, 2SJ554. As this low pressure on the tube, so with a pair of gold seal bassoon Motorola MJ15024, MJ15025 its slide-powered, so working in a constant state field pipe, not breakdown.
- The board adopts current advanced UPC1237 speaker protection circuit, make your speakers more secure.
- The amp sounds very outstanding, well worth a try!
 
- Note: To reduce the hassle of installing the heat sink you Shaoyou the board has brought a triangular aluminum thermal conductivity, thermal conductivity, but also need to pick 1.5KG triangular aluminum plate and heat sink, No side burn because of insufficient heat pipe.
 
- PCB size: 285 * 105MM
- Supply voltage: AC double 28V-34V, dual 34V/400 watts or more recommended
- Output power: 150W * 2
- Speaker Impedance :4-8 ohm
