*NOTE: Output (up to 1000 Watt Mono) amplifier circuit*
*This project needs huge aluminum heatsinks, since this is a push-pull amplifier circuit, it works very much depending on your loading (speakers)*
*This is a project that requires advanced knowledge of electronics related to audio. The cost of the project is relatively high. If your knowledge is not at a level where you can understand the project, you may fail and lose a good amount of money*
*If you are a beginner, we recommend starting with less complex and cheaper projects. Gradually you will gain the knowledge needed to make this type of amplifier😊*

Mind blown !! This is such a beautiful and powerful build. One of the best of your designs. Thank you for sharing this powerful and elegant amplifier. Will it be better to have a speaker protection relay as the pop on power on has a push on the speaker (its that powerful). How many heneries is the inductor ? can that be replaced with a output capacitor (35v-2200uf) ?
May i please request you build a similar Class A amp which has huge power just like this one ? Thank you again for your hardwork and for sharing your craft.

[@vodamvan4786]

Chờ mình Xem với nào hay quá

[@Uraim]

Testing an amplifier is about using a power resistor and measure output voltage to calculate the output power, instaed of the speaker. Vout*Vout/Resistor resistance (Due speaker have impedance, which will act different in every time, unlike a power resistor which is always x amount of ohm. )
Also i can tell its not 1000Watts, due the speaker wires are thin, and its not burning front of camera, its stays cold. (It might be due its on "30% volume") but i would consider use thick cables for this high performance. My guess is that amplifier puts out only 100Watts. Thats why the cables arent burnt.

You must have a switching power supply

[@sunarsihnadhifa5957]

Please you explain v - you give c 5200 transistor ?

[@ShareTechCreative]

Thank you for your attention, this is also a way to connect, usually, people see that the collector (C) of the transistor is powered, and the emitter (E) will output the signal to the speaker.
For example, The positive source is supplied to the collector pin (C) of the NPN transistor, and in this case, the source is negative, it is completely opposite.
This is also fundamental in the ways of biasing transistors.
Again you should also pay attention to the polarity of the power supply, which powers the amp. and you do it step by step, pay attention to supply the power within the allowable threshold it will work very well and powerfully... Good luck.!
