The fuse is blowing due to an overload. It's often and very likely caused by a transistor or ic that has gone short. The main culprits are the power transistors of the amp or whatever is on the big heat sink. Transistors will show the fault when you connect an ohmmeter to the terminals. It will be just like you have touched the test prods together! I don't think in your case it will be in the power supply. It's often caused by speaker cables that touch together.

If you have a digital meter set it to ohms and measure impedance at the speaker input, if you have a model number do a general search to find out more additional imformation.
