Published:2011/5/12 2:07:00 Author:Rebekka | Keyword: 300W high-fidelity power amplifier | From:SeekIC

The output power of the amplifier circuit is 300W when it is 8Ω load and BTL mono; When it is load 6Ω and the stereo outputs, the power is l00W + 100W. The circuit uses high-power amplifier LM21CL produced by National Semiconductor. It uses ordinary metal TO-3 package (size and general, like high-power transistor), the rated output power is 150W, the maximum supply voltage is 80V, the maximum output current is 10A, the circuit is shown as above.
