1.)What technique could I employ in repairing the dc outputs.

3.)The XFMR is in a copper color metal case.
3.) Copper-colored metal cases are common on most MRC power packs.
2.) Yes, it is fixable. You just need to replace the broken terminal strip.
1.) I'd use a screw terminal strip, also called a "barrier strip"as a replacement for the damaged terminals. These strips are made of black Bakelite and have rectangular silver plates with two screws in each plate, The plates are divided by raised Bakelite walls or barriers to keep adjacent wires from shorting to each other. They are sold by electronic parts dealers like www.allelectronics.com
Scroll down the left side to "terminal strips. Look at Cat.# TS-204 & TS-206.
With the power pack unplugged from the wall outlet, simply attach each of the DC output wires from your damaged strip to one of the terminal screws on the new strip. Then wires from the track can be attached to the second screw on each terminal. The strips have holes at each end for mounting them. Mark, center punch, and drill a hole for a screw at each end of the new strip. Be very careful not to drill one little bit further than you have to beyond the metal case. You don't want to drill into any electronics inside your power pack! Also do not use flat-head countersink-shaped wood/sheet metal screws to fasten the terminal strip to the case. Instead use round head, or pan head screws, & a small washer. Bakelite is very brittle. Driving a counter sink screw head into it will split the terminal strip at the mounting hole. Also don't screw in too tightly, also to prevent damage to the strip.
