Morning Charles
Not enough information here. What brand of radio do you have and what is the model number. A picture of the radio and the particular component would help us inentify the coil. On any given radio, a particular Coil or Can may very well be, as in your case L9, on another Radio it may be L6 or something else. f you have a problem sending a picture/s by the ususl method, just drag and drop then into the text portion of your post.
