John,

I am curious what kind of balun you were running that failed at 1500 watts?
The old high-gain BN-86's are notorious for failing, but as I recall you are
using a SteppIR antenna.

In addition to being a good all around reference on RFI, Jim Brown K9YC
has some good info on balun design in the following tutorial:

If you want something off-the-shelf that will hold up well, DX Engineering
has 10KW rated baluns designed by W8JI that should take anything you
can throw at them. There is a good balun technical reference on the DX
engineering site.
