Welcome to the new Furball Audio Vintage Audio Schematics page.

We've updated and grown the schematics list, most of the stuff that was missing is now present and everything is now FREE, we've removed the schematics and manuals from the store and published them for general availability. We'd like to encourage a wider dissemination of technical knowledge in the music biz and we'll gladly do anything we can to help raise the bar.

Below is a list of some of the schematics you'll find on oue site, the list is only partial and there's a lot more great stuff here. You can download these schematics for free, we do ask that you register on our site first, it won't cost you a penny and all we ask is your e-mail address so we can let you know when new products and services are available. To all those who helped support our site during the formative years, both spiritually and financially, a heartfelt thank you for your encouragement and generosity. We hope we're bringing you something useful and we look forward to becoming an established presence in this corner of the audio world.
