If you contact Energy/API/Klipsch they should be able to tell you if a repair is even possible. I would guess, judging by the age of the unit, that the amplifier is most likely no longer available, and by your report of its condition it may not be easily repairable.
If repair IS possible, then they should be able to give you a quote which will tell you whether it's worth it or not. As far as I can tell the unitwas big and had an MSRP of about $1600 when new.

Love that one!
