Any power supply will do as long as it has the same specs as the dead one, which will be:
Input : x Volts AC
Output: x Volts AC or DC
Watts: x
Amps: in millamps
Polarity: (for power supply with DC output only) Center pin = plus or Center pin = minus
You should be able to find the matching transformer/adapter/power supply at Radio Shack.
More info, let me know.

P.S. The power supply you received may be the correct one -- check to see if the specs match the old one.
Testimonial: "This situation is a little more complicated that a Radio Shack fix. Thanks anyway."

I just finished working on one, finally got it going. I checked every component on the powersupply board using a tracker, a simple circuit that when used with a scope with X and Y inputs, gives a characteristic curve of the component. Everything checked fine.
As a last resort, I jumpered out the on/off switch.
I had checked it with a meter. The unit came back to life.
The switch had failed internally.
Give it a try. I couldn't find a direct replacement so I mounted a toggle switch in the original switch opening. The customer is happy.
