KA2281 previously with various vu meter circuit I made , but all mono circuit stereo manufacturer has two channels has been a challenge but in the end a bit of trouble in the scheme worked beautifully :)
Original diagram 15, 16 pins between the 50k resistor connected in this way the circuit full does not work for an additional 15 numbered pin- 56k resistor 2 to pin connects seamlessly with all channels running ka2281 outputs 560 ohm resistor on the LED connecting optional 470 ohms can be used but lower values of the LEDs more disrupt the flow can lead to integrated pull . Mp4 audio inputs with 12v circuit works , cd player, pc etc. . resources , such as low power amp can be connected directly connected to the output does not
KA2281 gives mono output for the 10 LEDs 20 LEDs hooked ikşerl was fine ring-shaped LED placement sequencing also be mounted on a panel with the template I gave much better results if you give

100W Transistor Amplifier Circuit TIP3055
100w amp circuits 100w total output power of 50w per channel is not symmetric single source of supply for 63 volt dc supply transformer 43v ac suggested 8amp npn output transistors tip3055
Amplifier specific areas on the circuit diagram of the given values of the voltage VR1, VR2 potentiometer can adjust to these values. You can use in the supply circuit 6A10 diode or diode bridge may be ready KBU10M specified as advice uF filter capacitor 6800uF 4700uF (80v-100v) or higher (10000uF) use a value
