From Schematic to Sound: The Best Resources for Practical Audio Amplifier Circuit Projects (PDFs Included)
Practical Project Ideas
: Global negative feedback is often used to reduce distortion and stabilize gain .
(You need a proper driver stage before the MOSFETs – use an op-amp or discrete transistors.)
URL: sound-au.com He provides dozens of project PDFs (e.g., Project 3A - 60W MOSFET Amp). Each PDF includes a full PCB mirror image for etching.
Searching for reveals a hunger for more than just schematics—you want tested bill of materials (BOM), PCB layouts, oscilloscope readings, and troubleshooting guides.
: These are the active elements that perform the actual current and voltage amplification .
