US $2.03/piece Item Description Product profile: Using original Toshiba A1943/C5200 Pre input capacitors and inter stage coupling capacitors using the best imported capacitors. The precision resistance is selected and the main circuit adopts the high precision chip resistors with a precision of 1%, which ensures the good signal to noise ratio of the whole machine. PCB using 1.6mm thick double-sided plate, 2 a copper thickness, tin spraying process, to ensure that the size of the current through the performance of the good. First class PCB quality, first-class production technology. The voltage amplification factor is 31 times. The static current of each channel is 40MA working at AB CLASS. Small signal tube using the original TOSHIBA low noise tube, the original ON low noise tube as a source of current and voltage amplification, The output tube uses the original imported Toshiba A1943/C5200, each channel two to the output tube. Voltage requirements: within the DC DC -55V Power range: 8 ohm /120W PCB size: 145*46MM Item Pictures
