Amplifier Circuits

Car antenna amplifier is a small box which helps car radio to catch signal better. Radio signal sometimes are very weak like soft whisper where radio are not heard good. Amplifier make whisper loud so radio can hear clear. It is good for places where radio station is far or music have noise or crack […]

Did anyone suffer from trouble receiving radio signals through the cable connection? A cable booster also referred to as a cable radio amplifier would possibly be useful. The impulses passing through the cable lines are strengthened by this electrical circuit. Many channels are available through cable companies but sometimes interference or lengthy distances cause the […]

This article explains how to build a 35 watt amplifier circuit that is extra powerful. It uses a special chip called a TDA2030 in a special way to basically double the amps output. This makes the speaker sound much louder. Building circuits with high voltage can be dangerous. Do this under adult supervision and a […]

Cable TV channels use the thin wires to pass through. As these signals go further they start getting weaker. Similar to a little radio where a cable TV amplifier circuit boosts the signals strength. This makes it more possible, that viewers may get a clear signal. Circuit Working: Parts List: Component Quantity Resistors (All resistors are […]

An amplifier circuit that boosts sounds using special transistors known as MOSFETs is described in this article. The reason these transistors work well in amplifiers are as follows: Note: Compared to other projects this circuit is quite challenging. Circuit Working: Parts List: Component Quantity Resistors (All resistors are 1/4 watt unless specified) 47k 1 240Ω […]
