Thanks, Atlantic! So, if Logitech or Sean Adams or ... has these schematics available for the Boom, I hope, Logitech (or ...) can make them (again) available for the SB3? Please! These things are too good to throw away! Regarding to your circuit details: I have the schematics from the DAC itself (from TI). That's why I measured and identified the too low voltage at the DAC power feed as a possible problem. I also know where the 3.3V for the DAC are generated - but I don't know what happens in between - the PCB is too crowded to see where the 3.3V from the regulator go to the DAC - somewhere in between the problem seems to be. But again: Thanks for your help & information may be, this also can be pieced together..... So: Still my question to all ( esp LOGITECH) remains: ** Who can provide the circuit schematics of the SB3 (classic), esp audio part.....? ** Thanks, Heiner P.S. I also posted this - in the DIY section, but no replies there - tha's why I went 'one up' to the general discussion... - on the Logitech forum - no feedback there so far.... ------------------------------------------------------------------------ slimhase's Profile: http://forums.slimdevices.com/member.php?userid=31958 View this thread: http://forums.slimdevices.com/showthread.php?t=96520 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/discuss
