Intro

Hi and welcome to the AUDIO CIRCUIT [denmark] website, where you can find a huge selection (a total of app. 40.000 PDF’s/120 GB) of FREE audio related schematics and service manuals on both older and newer audio, HI-FI & PRO 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

Running 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 or whitelist this site. This way you help keeping this site free.
THANKS
