Hi! The top 12" speaker in my Hartke 2200 2x12 cab started crakling during sound check a couple weeks ago (this cab has kicked ass for over 10 years!). I popped the speaker out today to find that there is a fuse with a broken filament (it's on what I believe to be a crossover circuit board; the cab has a high freq tweeter). So I have a few questions: - Does anyone know where to find a replacement fuse for this cab? (the fuse doesn't specify what kind it is) - Would a blown fuse affect the 12" speakers (or just one, for that matter?) - What's the verdict for a 'crackling' speaker? Do I need a replacement, and if so, where can I find replacement Hartke speakers? (12" 8ohm 150w) I saw a post from 2010 with a very similar situation, but I didn't see the actual solution. Thanks in advance for everyones help!!!
