• DIY Audio Amplifier Schematics (375 KB .pdf document)
  Schematics and photos of a 68 watt per channel stereo amplifier I built more than 10 years ago. I still use it and it still sounds great.

These are hand-sketched drawings, scanned and saved to .pdf. Don't expect detailed instructions here (with the exception of the router table plan which goes into some detail). Some are little more than crude scribblings. What I have to offer are quick-and-dirty drawings that will get you going in the right direction. Besides, if you are like me, you will want to modify them to your own specifications anyway. Good luck and have fun.
