TOSHIBA 1943-5200 2.1 POWER AMPLIFIER BOARD (80W * 2 100W)

1 using the original TT1943/TT5200. 2 The main circuit of the electrolytic capacitor signal adopts the NOER brand name, the main filter capacitor adopts the NOER audio special capacitor capacity of 6×10000UF, adopts the rectifying flat bridge of 25A and above, and guarantees a steady stream of powerful power support. 3 resistors use five-ring metal resistors, the main circuit uses precision ± 1% of the five-ring metal film resistors to ensure a good overall signal to noise ratio. 4 PCB adopts 1.6mm thick double-sided plate, 2.0oz copper thickness, spray tin process, to ensure the good performance of the size of the current through. First-class PCB quality. 5 This board comes with a horn protection circuit to effectively eliminate the boot impact sound and better protect your horn. . 6 I think that the use of the subwoofer for the tube is better than that of the IC, and the intensity of the play is large and not as loose as the IC. Basic parameters:      PCB size: 230*104mm (width without potentiometer handle length)     Transformer: AC dual 28V-32V/200 watts (amplifier power supply), AC dual 12V or 15V (pre-power)     Output power: 80W*2 100W     Speaker impedance: 4-8 ohms
