Driving a site like this costs time and money plus sleepless nights, when the site goes down due to brute force attacks and malfunctioning plugin updates etc. 

So every of kind of support is highly valued – that be a small donation through PayPal or you disabling your ad-blocker and clicking on some of the ads presented. This way you help keeping this site free.



Hello and welcome to AUDIO CIRCUIT [denmark] website, where you can find a huge selection (a total of app. 10 GB) of FREE audio related schematics and service manuals on both older and newer HI-FI gear.

I started this FREE service back in 2004, and it has been online ever since – only interrupted for some shorter periods due to bandwidth abuse. To avoid this from happening again, I have made this service available only to registered users. But don’t worry – it is absolutely FREE to register 🙂

If you have already registered, then please go to the Login page. As this service is very time consuming, I can only encourage you to support this project by making a small donation via the PayPal donation button in the top corners, whenever this free service has helped you.

If you are you new here, please go to Register page and register for FREE, so you are able to use the download function!

I have also added a short Help section, that describes how this sharing site is working…

Share with others
If you have a schematic or service manual, which is not in my download lists, then please use the Share/Upload function.
