Maybe that is my problem. I definitely have a problem. I am able to get the EFC to work on some occasions. Usually it will work if I run the trimmer all the way out and toggle the power. I can then adjust the trimmer and get things working. But if I give the box a rap the frequency jumps and I get into the "mode" of the EFC not working. I can trimmer it up and it will look fine but no EFC.
I will check out that ferule thing. I'm not sure what you are describing but will look for it.
