Nah...those specs are on the label of my dead power
adapter. That's not the problem.

Radio Shack doesn't stock replacement jacks that style and
size...I checked. The solution would be to use the wire/jack
from the dead adapter.

..and then there is the auto-cutoff circuitry which stops
charging the battery when the computer thinks it's full.
FYI, I checked digikey.com. The closest AC Power Adapter
they had was $82.80, nearly twice that of MCE's Mac
proprietary version for my machine at $44.00
.but thanks so much for the Re. You never know 'til you try.
