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:

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:

This circuit have some problems after 4 to 5 min power transistor dead

no, please see at circuit diagram. There is no erorr, you must adjust bias voltage.

it can work normally not just a minute.

Good amplifier and thanks for your video

youre wellcome, and say thanks for visit

we are happy to comment here, and we await your komantar in our blog

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

I saw some other videos the same circuit but there is no trimpot or bias circuit

Q14=TIP2955/2SA1962
Q15=TIP3055/2SC5242
you can choose these transistor

the power amplifier is work, you can see the video testing amplifier

yes, the circuit is no trimpot bias setting.

But on the assembling video i saw there is bias tripot I'm confused, but anyway thanks a lot for sharing this powerful amp i will try to build very soon. Thanks a lot god bless..

what are the sizes of the PCB?

hai i want pcb and components all so price please my email id: cool.pvk@gmail.com

how to adjust the trimpot in the amplifier driver

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

hi how are you can you tell me how to download the PDF, thanks

You can change the emitter resistor by using 220R 1w. and also the npn transistor

the pdf file is in stereo yiroshi amp post

Sir what voltage should I use for 12pairs 5200/2943 transistor output?

Can I use IRFP240 and IRFP9240 for this project?

yes im using 110V its normally. but you must have larger heatsink

you can use up to 100v for more performance

It can't if you use final mosfet. see class d d4k5 its bigger power than this amp. if you want mosfet class d amp
