ATTACK IT WITH a DREMEL microdisc abrasive disc (like what you saw on
their ad cut thru a
nail...there are heavier ones made of diamond impregnated metal

like a A baby air chisel

Franlkly tho wall warts are so cheap it's easier to replace it...but
it's almost BETTER to make a simple 3-terminal regulator in a minibox
Parts: diode-bridge chip
bias resistor or potentiometer
xfmr
filter capacitor
load resisitor
pcb substrate

are very dangerous.
