TDA7294 80W 100W Mono Audio AMP Amplifier Board DC30V40V K

All resistors are 1% precision metal film resistors, capacitors for , ruby ​​ capacitance, polarity , 1UF capacitor using WIMA capacitors.
The new TDA7294 chip; KB level PCB board, all components have been marked in the screen printing plate, easy to install DIY .
The front-end rectifier filter after the power input terminal (note the supply voltage polarity can not be reversed, otherwise the chip burn!) To the right of mono output.
The board compatible TDA7294 chip, the key is C4 capacitor pment, the board has indicated, this design is a major feature of the restaurant board.
Note that the chip is connected to a negative voltage of housing, insulated between the chip and heat sink fins otherwise met with a negative voltage due to malfunction or other cause IC circuit burned, ! !
