Amplifier Circuits

Car Antenna Amplifier Circuit 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 […]

Anyone having problem getting radio signal from cable? Maybe this post for Booster Circuit for Cable Radio can help which is also called cable radio amplifier. This thing make signal strong when going through cable. Cable company give many channels but sometimes signal is not good because of too much distance or interference. Because of […]

This 35 Watt Bridge Amplifier Circuit using TDA2030 IC show how to make 35 watt amplifier circuit. This circuit is very powerful. It uses one special chip named TDA2030 but is used for different way to make double power output. This make speaker sound more loud. Be careful circuit uses high voltage and it can […]

Cable TV Amplifier Circuit uses small wire to send signal. When signal goes far it become weak. Like small radio, cable TV amplifier make signal strong again. This helps people get better and clear picture. Circuit Working: Parts List: Component Quantity Resistors (All resistors are 1/4 watt) 680Ω 1 820Ω 1 75Ω 1 100Ω 1 […]

70 Watt Audio Amplifier Circuit teaches us about one amplifier circuit. It makes sound louder using special parts call MOSFETs which is the type of transistor. Why this transistor is good for amplifier: Note: This circuit is little hard to make than the other projects. Circuit Working: Parts List: Component Quantity Resistors (All resistors are […]
