| This is a bare PCB of a stereo power amplifier. The power amplifier stage uses LM4780, which is one of the most popular and good-sounding power amp chip. The input is buffered by a triode tube for best musicality performance. The tube can be a 6DJ8, 6922 or 6N11. The board design is so compact that the input and output connectors can be directly soldered onto the PCB and mounted onto the back panel of the chassis to maximize space. The board also includes a small volume control PCB board. The board can fit a Alps RK27 potentiometer. We do air shipping worldwide at US$6.00. |
