  • 3 year old 5E3 Build blowing fuses intantly

    This is probably a silly question, but I need some feedback before I spend the money. I have a 3 year old 5E3 build with a Weber 02513 PT that has started instantly blowing fuses upon start up. It did this even with all the tubes pulled, so I totally disconnected the secondary wires. The fuse still blows instantly. Is it safe to assume that this transformer is toast? Thanks for your input!

    I would say yes. You did a good troubleshooting job.

      Not yet, disconnect the PT primary wires too, just to make sure there is not some short in the primary wiring (power cord, switch, fuse holder, etc)

      But probably toast.
