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 […]

2 watts amplifier schematic diagram

The amplifier is designed for independent in a small speaker box. Can support to Walkman, Mini-Disc and CD players, computers, and similar devices with line or headphone output. Of course, in many cases, you will need to create two units for stereo. The circuit is intentionally designed using old type transistor, it is to get […]

100 W audio amplifier based LM12CLK

The 100W audio power amplifier is powered by the integrated circuit LM12CLK which is operational power amplifier. The monolithic IC can deliver 80W of sine wave power into 4Ω load with 0.01% distortion. Power bandwidth is 60 kHz .. Important features of IC LM12CLK include : controlled turn on, overvoltage shutdown, output-current limiting, dynamic safe-area […]
