Yes, I've autopsied a few blown BN-86 baluns in the last 30 years <G>.

Notice the "Current Balun" in the upper right is a different type face 
than the rest of the manual.  I think someone is playing marketing 
games (unless they removed the third winding in the last few years. 

The better balun is the BN-4000 which is a "W2DU type" device.  I have 
not know one of them to fail but I haven't seen any test data on it 
either.
