Yes, Don, unfortunately.  If you had the factory standard 2 Amp fuse in there, you may have a more serious problem than just the transformer.  I recommend a smaller fuse (1 Amp, fast blow) or adding a fuse to the transformer secondary.  

In my case, the G-5400 culprit was the motor on the elevation rotor.  When it failed (locked up), the current overheated the transformer until it failed.  Then the fuse blows.  Bad design.
