Another example from my blown up shit collection, pictures archive:
Burned out harmonic filter, BE FM-30T transmitter
The harmonic filter from a Broadcast Electronics FM-30T. This actually started in the bullet connector to the 3 inch hardline on the output side of the filter.
Burned out 3 inch hard line section
Again, I did not install this myself, someone else did. Cutting 3 inch hard line is pretty straight forward. When using a field flange, the outer and inner conductors are cut flush. Both conductors should be de-burred and filed smooth. It only takes a little thing to start an arc with 30 KW of FM power, so once again, attention to detail is key to avoiding these things.
Fortunately, BE sent along replacement parts for the harmonic filter and the line section was replaced.
