100W Power Audio Amplifier Diagram based FET K134 and J49

100W Power Audio Amplifier Diagram based FET K134 and J49
Here is the 100W power audio amplifier circuit diagram build based on a pair of FET component on final amplifying process. The FET components using a pair of K134 and J49, the substitutes for these FETs are the combination of J162 and K1058. The output power will be about 100W at 8 ohms speaker. For stereo application, you should build two similar circuit. (more…)

100W Audio Amplifier based F.E.T

100W Audio Amplifier based F.E.T
This 100W Audio Amplifier design uses two V-MOSFET transistor technology as the output stage, delivering 100W in output, with a 4 Ω load. It is important that the transistor of the output stage, kept cool by adding a heatsink or fan for example. (more…)
