Other Features
Support CD/VCD/DVD/MP3X-10D designed and more stable than original one, digital tube increase by ten percent; This board 12V AC input, through circuit processing, provide 6J1 digital tube needed positive and nagtive voltage and supply voltage of lamp filamentWorking principle: Once open power supply, lamp filament begin heating, voltage also boost from 0, they will finish in the same time; The same with bile rectifier, 8 PCS 470uF capacitor filtering is very clean; Clean power supply system don't generate AC soundStandard connection method: CD ~ preceding stage P5-1 ~ your amplifier ~ speaker
