100W Guitar Amplifier
The amp is rated at 100W into a 4 Ohms load, as this is typical of a "combo" type amp with two 8 Ohm speakers in parallel. Alternatively, you can run the amp into a "quad" box (4 x 8...
4 Watt audio Amplifier
The circuit is very simple and incorporates darlington output transistors that will provide more than enough output current than is needed to drive a 3-ohm speaker. The gain may be pre-set for a variety of input levels, making it suitable...
6W-audio-amplifier-with-preamp
This monolithic IC, class-B audio amplifier circuit is a 6-W car radio amplifier for use with 4-ohm and 2-ohm load impedances.
The monolithic integrated circuit (IC) described is designed to function as a Class-B audio amplifier, specifically tailored for car...
Trainwreck Blues tube amplifier for Guitars
This revision reduced the signal level and treble response in the preamp for a smoother sound in both cathode and fixed bias modes. The power supply was also revised for lower B+ voltages to the EL84 plates. This amp was...
