I sent MFJ/HyGain a set of photos a couple of months back of the balun which came from my TH7DX. The contact at the connector flange was totally corroded and the wire around the ferrite was burned/arced across 3-4 turns.  It was also the home for the central OR coast spider population. this is the response I received.

“This design is at least 30 years old. The current version uses an entirely different design. The BN-4000B is the same, but 4kw PEP or 2KW average.”

There was no further elaboration on what the current different design was. Someone know? I chose to replace it with a Balun Designs unit.
