The first schematic describes a 100 watt Guitar amplifier circuit which can be used mainly for amplifying guitar sound and also a public address systems. The next schematic in this article explains yet another guitar amplifier enhanced with fuzz effect generator and treble booster circuits. To test its ruggedness, the unit is designed without any […]

Make this Bass Booster Speaker Box
In this article I have explained the construction of the high bass boost speaker box system, which can be used for reproducing music with heavy bass effect, which can be adjusted with a potentiometer. By: Alfy Mackenzie Most of the affordable hi-fi systems in the market have decent mid-range and treble feedback but do not […]
4 Efficient PWM Amplifier Circuits Explained
Audio amplifiers which are designed to amplify an analogue audio signal through pulse width modulation or PWM processing and with adjustable duty cycle is known by many names including digital amplifier, Class-D amplifier, switched amplifier and PWM amplifier. (Article Contributed by: Ritu khanna) Because it can perform at high efficiencies, a Class-D amplifier has become […]
Electronic Drum Sound Simulator Circuits
In this post we talk about a couple electronic drum sound simulator circuits which can be used for replicating actual drum beat sound electronically, using a few op amps and few other passive electronic components. Using Capacitor as the Sensor Instead of Piezo Conventional electronic drum kits incorporate the use of piezo disc affixed to […]
RF Amplifier Circuits and RF Converters
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 […]
Extended High Bass Effect from Small Speaker Box [Cross-Over-Filter]
Bigger speaker boxes produce proportionately higher bass effect, this fact is know to all of us. However, bigger boxes are not only expensive, they can be cumbersome and bulky. How about having the very same high bass effect, that a bigger box would provide, from a much smaller and compact speaker enclosure? Sounds strange right? […]
