Does this need to be sent back into Alembic, or can a local repair guy possibly fix it? pace Senior Member Username: pace Post Number: 491 Registered: 4-2004 Posted on Sunday, January 10, 2010 - 5:41 am:    Im pretty sure all that's in there is a step-down transformer, some diodes and filter caps.... If you have a meter that can check for continuity, chances are you'd isolate the problem component or lead. keith_h Senior Member Username: keith_h Post Number: 1484 Registered: 2-2005 Posted on Sunday, January 10, 2010 - 7:15 am:    Any local tech should be able to repair it. Here is a link to a thread with a schematic of the power supply. Mica also talks about sourcing the transformer.

Try jiggling these spots and see if your LEDs light up. Replacing the plug is simple, the grommet end is bit tougher but not impossible.

I just bypassed it like on the older ones. Michael
