Just asking, but did you disconnect all inputs and outputs? This way you will be sure that another item connected to your preamp is not causing the fuse to blow.
Maybe you have a shorted interconnect.

Preamp repeatedly blows fuses
I've got an Antique Sound USA PA-5 preamp from 1997 that keeps blowing fuses. I originally found the problem last night when I walked away from my chair and came back to find the preamp dead.
I immediately pulled the fuse and it was an "F3A250V" quick blow. I replaced it this afternoon and as soon as I turned on the preamp, it blew the new fuse. No fireworks, no pops, just a dead preamp.
I don't know where to go next, other than to call my local tube amp repair shop.
Any thoughts?
