Please post a circuit design diagram, if somebody has it. Thanks in advance! paologatto Try using this http://www.diyaudio.com/forums/search.php?s= function and you'll find something.. ;) peranders Did you find anything interesting? tobias_svensk http://home.swipnet.se/~w-50719/hifi/qrv07/index.html http://www6.head-fi.org/forums/show...ghlight=tpa6120 http://www6.head-fi.org/forums/showthread.php?t=185795 head_spaz I'm not sure exactly what you're looking for, but Rod Elliott has a nice prototype headphone amp listed in his article ESP -- High Speed Amplifiers in Audio     (shown about halfway down the page). I should point out that it is based upon the THS6012 instead of the TPA6120, but you might find his application useful, and perhaps find the answers you are seeking. Best regards, David peranders The THS6012 and TPA6120 is more or less the same part. It may be a case of taking different prices for different markets.
