Relatively easy to build up to 30W Amp OTL by TDA2030 transistor is packed into this project.the power dissipation of 20W at 8 ohm or 30W at load 4 ohm
This is the Class G 300 watt MOSFET Power amplifier circuit with PCB MOSFET. It have more feature, maximum RMS output power: 200 watts at load 8 ohms or 360 watts at the load 4 ohms.
This is a transistor equalizer circuit. We use it for controlling the audio frequency. Because some kinds of audio frequency response are not smooth. It helps a frequency offset in a tone control…
These are Tone control circuit using op amp - NE5532 or 4558 IC as low noise, with PCB layout, can adjust sound frequency and tone bass, treble, mid and..
