There are MANY more likely components than the transformer that will cause the fuse to blow.
Most common are filter capacitors, rectifier diodes, and shorted components in the power amp section.
Transformer failure is very UN-likely. Have a competent electronic tech troubleshoot the unit.
When testing the unit, put a 150 watt light bulb in series with the power line... saves fuses during troubleshooting. This limits the current so one can analyze the real cause of the problem.

If you put in headphones in the amp headphone output, and there's a sound, it's probably the output amp (IC1 - TDA7293V) that's bad from the fan failure, if not cooled proberly failure is doomed to happen. Replace fan and output part, and you should have an amp up and running again.
