Energy EW-100 Subwoofer transformer
 
I have a dead powered sub. The transformer is stamped
042-010078-000ZR. I have no idea what I need to repair or how to determine a value for replacement. Does anybody have a schematic? Can I repair this. There appears to be continuity in the primaries but no output. The amp is said to have 225 Watts secondaries are center tapped.
Thanks

Look thruout the inside of the unit, use a decent magnifying glass...look very closely ... take lots of pictures, close-ups ...post them here.Someone might have seen such an amp. Sometimes the amp section will have voltages written on the PCB coming in from the PS....EG. +35V -35V
It is a starting point at least...Klipsch will want to repair it for you of course$$...and surely wont tell you the specs on the transformer..nor is their likely a schematic easily available.

did you ever find about the transformer voltages, etc? I have a Klipsch that has the exact same problem... an open winding in the power transformer.
