DIY Stereo Yiroshi Power Amplifier 1400W

<br /><br /><br />This my second project for Yiroshi Power Amplifier Circuit, power amplifier circuit is indeed very super quality, many have tested the strength of this Yiroshi power amplifier. Power amplifier yiroshi is suitable for outdoor or indoor. Previously I have made this yiroshi amp circuit in the mono version. I have also tested it in the unboxed state of the box, using only 2SC2922 and 2SA1943 final

DIY 500W Class-D TL494 Switching Amplifier

<br /><br /><br />In this project, I will share about class-d power amplifier using TL494 IC for PWM, and use N-Channel MOSFET transistor as the final amplifier. This circuit is not so complicated and cheap to make practice making power amplifier class-d. This power amplifier circuit can be supplied with 30V to 100V DC asymmetric power supply using 8VDC bias voltage up to 12VDC. For the output power of this

Speaker Protector 3 Transistors

<br />This speaker protector circuit serves to protect the loudspeaker from the DC voltage that flows from the power amplifier, especially from the type of OCL power amplifier. In fact the working system of the protector speaker circuit is simply delaying the connection between the amplifier and loudspeaker output for a few seconds. When the power amplifier is first turned on, there is usually a
