All resistors are 1% precision metal film resistors, s for Nikon, ruby fever capacitance, polarity Philips CBB, 1UF using German WIMA s. The new imported TDA7294 chip; KB level PCB board, all components have been marked in the screen printing plate, easy to install DIY friends. 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 easily compatible TDA7294 chip, the key is C4 placement, 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, please well insulated between the chip and heat sink fins otherwise easily met with a negative voltage due to malfunction or other cause IC circuit burned, remember! !
