DIY and Hi-Fi Audio Schematics

This is our collection of DIY and Hi-Fi Audio Schematics. Feel free to send us your hi-fi audio schematics and we will add them here. If you have built any of these circuits, we would love to hear from you so send us your comments.

Many of these diy Audio Books contain schematics. You can also find more schematics through some of the sites noted on the DIY Audio Links page.
