200W Mono Amplifier Board for 2 Pair of 2SC5200+2SA1943 as Main Output TRANSISTORS.

You can purchase it. This product is fine. I am using it with 300 watt subwoofer. Deep bass and very very power ful board. Your input gain should be proper with this board. Used the 30-0-30 transforer 7 amp, and 50 volt 8 pieces keltron capacitor. Awesome result, like a professional sound system.

Sound quality 👍 good 🥰 Circuit diagram and DC Offcet 100% perfect

defected product , some parts short. asemble not good. ghatiya manufacture "Extremely disappointed with this product. The build quality is sub-standard, and the manufacturer failed to include thermal paste on the transistors. Definitely not worth the price." audio input and output voltage very high, defected circuit board . "I am very disappointed with this board. After receiving the product, the amplifier was not working correctly and showing high DC voltage at the output. Upon a detailed technical inspection of the PCB, I discovered a major manufacturing blunder: the transistors were installed in the wrong positions. Specifically, the board has markings for two A1015 (PNP) and one C1815 (NPN) transistors. However, the manufacturer sent the board with two C1815s where A1015s should be, and vice versa. This is a critical error that can easily burn the power transistors (5200/1943) and destroy connected speakers. I had to desolder and fix the transistor placements myself to make the board functional. If you are not an expert in electronics, do not buy this, as it comes with wrong connections from the factory. Very poor quality control!"

I just received a product going to test then will see how was product ...... After testing product was so good and power full I'm using 35 0 35 12v convertor borad for 12v uski psu power supply 18amp working greeet

I bought this unit for salvaging the heatsink and power transistors for one of my projects. I am happy that the supplied heatsink is of good quality. The kit consists of cdil power transistors, other parts not very good quality. Also no fittings for connectors and terminals are absent. Overall I'd consider this slightly expensive for the quality. I'd imagine you should need a good rectifier unit to power this.

Very powerful amplifier board, I am connected Pioneer 12" subwoofer. Please note: 2 output power supply must required ( 24-0-24 to 30-0-30)

OK but heavy heating

Bad
