If the amp blows the fuse at power up, then the usual causes are (in order of occurence):
#1- Shorted Output Transistors
#2- Shorted Power Supply Rectifier
#3- Shorted Power Transformer.
Of course there can be a million other things as well.
I don't know how experienced you are, but if you don't know what you are doing, working on any line powered device can hurt or kill you. If you feel qualified, check the listed items. If you don't feel qualified, take the amp into the shop.

Of my three 250 heads only one that I perchased used had a blown output section, but the the fuse never blew. My guess would be that the output section is blown, which took out the bridge rectifier, which took out the fuse.I checked and it is a 3 amp slowblo fuse.
