This is Sound effects two tone circuit, which generally abound measure various both of kinds use IC frequency origin oruse the transistor. The sound will that is proportionate big depend…
Do you love music? Imagine we can build power amplifiers system. Sound good, doesn’t it? Here are many circuits. For example, about Audio amplifiers, bridge amplifier, Using transistor or IC or MOSFET, Mixer, Graphic Equalizer, Preamplifiers. And, Sound generators, tone controls, Melodies, Sirens, Animal sound, effect voices. Even, Burglar alarm, and more. I cannot explain to you all. But sure I do not like to see you miss them.
2 Circuits of High power transistor amplifier circuits, 200 watts and 300 watts RMS
Although it is ancient, it is still interesting.
Simple MOSFET Amplifier Circuit easy make!
This is a TDA2030 Bridge amplifier circuit diagram with PCB. It gives an output power of 35 watts to 40 watts at 8 ohms speaker. With using a +/- 15V…
This is Bass treble tone control circuit diagram as ideas, we have two circuits both transistors ,ICs-op amp as main, so smaller, but high gain signal.
This is TBA820m Amplifier circuit stereo 2W+2W, supply voltage 12V, Easy to build and cheap. on DIP-8pins same LM386. but TBA820M use easy better. [...]
