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...
14 Watt Audio Amplifier
The audio amplifier shown below provides 14 watts of power, but can provide much more simply by increasing the power supply voltage. This amp was built in 1975 and has worked reliably ever since. The power amp portion was published...
20 Watt audio Amplifier
This is a standard amplifier based on LM 1875. It can deliver 20 W, with an 8 Ω speaker and 60V power supply even 30 W.
The capacitors C4 and C5 should preferably be as close to the IC down. More:...
LA4440 audio amplifier circuit design electronic project
The LA4440 audio amplifier IC can be utilized to design a straightforward stereo power audio amplifier project, capable of delivering 6 watts of output power into an 8-ohm load. This audio amplifier IC features a minimal number of external components,...
120 Watt Audio Power Amplifier Circuit
Amplifier with IC number TDA7293 for processing sound systems. This amplifier includes inputs for a radio, TV, stereo, or other line-level devices. It also features a phono input for a record player, guitar, microphone, or other unamplified sources. With the...
7W Audio Power Amplifier LF356
The circuit depicted is a low-frequency output 7W power amplifier. It employs a FET input operational amplifier, the LF356, for voltage amplification. The design features a transistor amplifier circuit that includes a driver stage. A significant negative feedback loop is...
electronic circuit amplifier
The TDA7383 features a fully complementary PNP/NPN output configuration, enabling a rail-to-rail output voltage swing without the need for bootstrap capacitors. This design significantly reduces the component count, allowing for compact assemblies. An integrated clipping detector facilitates gain compression operations,...
Walkman amplifier
The gain of the low-cost IC is internally fixed at no less than 34 dB (50 times). A unique input stage allows input signals to be referenced to ground. The output is automatically self-centering to one-half the supply voltage and...
Audio Signal Testing amplifier
This mini audio amplifier will test the audio stages in amplifiers such as the front end of FM bugs. You can also use it on lots of our other projects as well as the output stages of radios. It is...
