This power amplifier OCL circuit delivering a blasting 300 watts to a 4 Ohm speaker. 300 Watt OCL Audio Amplifier Circuit The amplifier...
300W Power Amplifier For Subwoofer

The 300W Amplifier circuit is shown it is a reasonably conventional design. Connections are provided for the Internal SIM, and filtering is provided for RF protection (R1, C2). The input is via a 4.7uF bipolar cap, as this provides lots of capacitance in a small size. Because of the impedance, little or no degradation of sound will be apparent....
20 Watt Class-A Power Amplifier

The amplifier circuit uses the basic circuitry of the 70W power amplifier, but modified for true Class-A operation - it should be pretty nice! This amp has been built by several readers, and the reports I have received have been very positive. With simulations, everything appears to be as expected, but although I have yet to actually build...
70 Watt Power Amplifier Using 2N30055|MJE2955

The 70 watt amplifier circuit is pretty much original, and with a +/-35V supply as shown, will provide 70W into 8 Ohms quite happily. In its lifetime, many of the mods mentioned above were made anyway, since I could never find the circuit diagram when I needed it, so often made it up as I went along! It is a fair testament to the amp that...
