In this article I have explained a few high frequency RF converter and preamplifier circuit designs which can be used for amplifying or enhancing the reception of an existing RF receiver. All the RF amplifier circuits provided below are intended to be placed near an existing amateur radio receiver or a matching radio set in […]

Bench Amplifier Circuit
A bench amplifier is a small test amplifier which includes basically all the features that are required for testing the performance of an input audio signal. It can be also customized as per the specifications of the input signal, so that you don’t have to build different sets of amplifiers for different test purposes. A […]
60 Watt Amplifier Circuit
The circuit of a 60 watt power amplifier is shown in the below figure. It’s design layout is simple and very conventional. It has a completely symmetrical pattern which has one pole frequency compensation, yet some uncommon methods have been employed in order to keep the number of parts less. To start with, the configuration […]
22 Watt Stereo Amplifier Circuit using TDA1554
The IC TDA1554 based Amplifier circuit discussed in this article can provide up to 22 watts per channel into a couple of four-ohm loudspeakers. The main attraction is that you can construct it for less than $15. This implies that you may make a power amplifier for your car’s front speakers, another for the back […]
Crystal Radio Sets with Amplifier Circuit
A crystal radio receiver, often known as a crystal set, is a simplest form of radio receiver that was widely used in the initial periods of radio. A crystal radio set does not require any external power supply to operate. Instead, it simply makes sound using the energy of the radio signals that is received. […]
Simple 150 Watt Amplifier Circuit using Transistors
This 150 watt amplifier is designed to provide a full 150 watt peak to peak music power amplification over a 4 ohm loudspeaker. In this post I have explained how to make a simple 150 watt power amplifier circuit using a typical OCL design which ensures cheap layout and use of minimum components, with high […]
