OddWatt Audio 5751 SRPP / KT88 Push-Pull Monoblock Tube Amplifier Kits
One of the advantages of hosting a hobby website is the opportunity to connect with individuals via email who share similar interests. Since posting Bruce's initial OddWatt project on the site, communication has occurred with numerous DIY hobbyists who have...
741 Astable Timer
In this circuit, a standard operational amplifier (op-amp) is configured as an astable multivibrator. The output is non-symmetrical, but it has the advantage of being controlled by only one resistor and one capacitor: a 100k variable resistor (U2) and a...
A New Audio Amplifier Circuit Design
The problem with class-B amplifier design is that we start with an output stage in two halves, each with a non-linear response, which we then add together to try to give a linear response, i.e. so that a graph of...
1Watt audio amplifier
Here is a simple audio amplifier circuit that is easy to build and has few components. This circuit is built around the LM386 audio amplifier integrated circuit, useful when you need to power medium-sized speakers from a music player that...
