Topic summary

The discussion centers on designing a 100W transistor audio amplifier with stereo output (50W per channel), microphone input, and a 3-band equalizer (bass, mid, treble). The original poster requests a schematic without integrated circuits, covering a frequency range approximately 20Hz to 20kHz. Responses include a direct link to a 100W transistor amplifier schematic using MJ15003 and MJ15004 transistors. Contributors highlight the complexity of such a project for beginners, emphasizing the need for foundational electronics knowledge before attempting a large-scale design involving multiple stages: microphone preamplifier, headphone preamplifier, pre-driver, audio mixer, tone control, power amplifier, and power supply. Suggestions include studying basic electronics through free online courses and starting with simpler projects. Some responses note the practicality of purchasing ready-made amplifiers due to cost and design challenges. The discussion also touches on the difficulty of obtaining free professional design help and the value of investing time in learning electronics fundamentals.
