Guest peter Posted December 19, 2003 Report Share Posted December 19, 2003 Sure hope somebody looking in on this post can help out.I'm trying to repair a friend's powered Advents (APLS Legends).The woofer PA lunched on one of them... I've replaced the outputtransistors, and three torched resistors, and have checked throughall the semiconductors, caps and connection-points... but thebias will not set (shows residual noise only, like a few uV @all biaspot wiper settings). I'm stumped now, and without areadable schematic (I have one, but I can't read any of thecomponent IDs or values) I'm probably going to stay that way.Does *anybody* have a legible set of schematics for thesethings?I've tried Sam's Photofacts... no soap. Can't find any otherreferences to the schematics except at the fisherdoctor site(which is where I got mine - take a look @http://fisherdoctor.com/advents.htmlThanks for your help...
