The original well cooked power supply is only a single 12V 2A power supply, the leads on the power connector are in parallel to supply the 2A. Likely any power supply that gives 2A will work there, and the original one likely will work again with the input fuse ( black heat shrinked item marked F1), the 4 diodes and the small electrolytic capacitor C2, C3 and the bulging capacitors on the output side, likely C13, being replaced.
