If a replacement from the factory is not available, do a quick reverse engineering of the power supply.

Start by taking the voltage rating of the main filter caps, reduce that number by a few volts and then multiply by 0.7. This will give you an approximate transformer secondary voltage. From here you can see if any transformers come close to what you need.
