50W audio amplifier 2N3055

January 29, 2009 amplifier 4 comments

A very simple power amplifier circuit built with 741, 2N3053, 2N4037, 2N3055 and MJ2955 which deliver up to 50W on a 8Ω speaker.
If you want to amplify lower frequencies increase the 4.7uF capacitor from the audio input or decrease it if you want to favour higher frequencies.
Use a 3A symmetric power supply for mono application and a 5A for stereo power amplifiers. Please take good precaution when use this audio amplifier : do not shortcircuit the output or not connect speakers ! Always check twice !
