    That's one of the things on my list too. I'm planning on hot rodding my 7A's eventually...upgraded XO's, mortite, dynamat, better binding posts...the whole works. I'm gonna bypass the fuses when I do that. I don't listen at completely ear shattering levels, so I don't really think I need the extra protection.

    Is there any easy way to bypass the fuse temporarily/permanently without upgrading the whole cross over?

    If you pull the terminal cup and connect the (2) leads together that hook up to the fuse holder end. There may or may not be a lot of glue in there. I believe based on my 5B x-overs you can connect them together close to the board. Use solder and electrical tape or the best is some shrink tubing to secure and protect the exposed ends.

    The tweeter is borked. Swapped the tweeters. Problem followed. Therefore, it's the tweeter (assembly).

    So, moving forward, is there any way to 'fix' or 'diagnose' the tweeter other than 'yep, it's not working properly?'

    I may just put up with it for a while, because it's still not very noticeable. It's odd, the distortion gets more pronounced when the recording is more distorted. For example, some of the accoustic stuff I was listening to I could hardly hear the distortion and most of the time it sounded completely normal. But, on another test cd (Frampton comes alive) the distortion in the tweeter ('bad' distortion) was very noticeable when the distorted guitar rifts kicked in ('good' distortion). Might be my mind playing tricks on me, but I don't know.

    I'll keep my eye on fleabay, the FM and CL.

    Thanks again to everyone who helped 'answer' this question. Now the fixing is up to me :D

    Yep...sounds like you need to replace the tweeter.

    The reason it sounds more distorted at certain times is probably due to it being driven harder during certain passages, such as the distorted guitar you mentioned. Acoustic guitar is primarily a mid-range instrument, so you wouldn't notice the distortion as much as with a higher pitched, distorted electric guitar.
