Hi Jeff:

Double and triple check the switchmode transformer connections.  There have
been more than a few with very tiny cracks.  This can eat the IC or blow the
fuse.

One of the strangest regulator problems I had was a leaky bridge diode.
That was a bear.  It did not cause the IC to fail though.
