Super Power Amplifier Yiroshi Audio - 1000 Watt

Super Power Amplifier Yiroshi Audio 1000W
This Yiroshi audio power amplifier has a low character and has high power output, so many audio lovers choose this type of amplifier because the bass boom is very pronounced. To make this Yiroshi audio amplifier so powerful need a power supply which is sufficient to let the results that can at maximum transformer minimum 20A 45-75v output and the good quality of components.

Below the circuit diagram of Yiroshi audio power amplifier driver + final transistors:

Wiring Diagram Driver Power Amplifier and Final Power Transistor

For this Yiroshi power amplifier project, I make a separate PCB driver with the final transistor, you can see on both picture PCB Layout above. The power amplifier is very good and high performance. You can upgrade again to add power amplifier by adding the final transistor and also replace it with more power, current, and stronger voltage. And also must be balanced with a larger power supply current and voltage. For more details see the full interesting video below:

  5. Hello,
    The amp as shown in schematics will NOT work. Q15 should be NPN type, prrobably TIP3055, although I think this is a bad choice as TIP3055/TIP2955 have Vce max of only 70V.
    Cheers

  11. Hi sir romadhon, I'm back after building this power amp it sounds nice even though i tested it on 65v 8.5A so not enough power supply. Im Wondering on the pnp final output power they are warmer than the npn output i have noticed the predriver 2SA1837 for pnp output is warmer also is this normal? Because still sounds good or maybe i will get problems in the future. Please help
