Hello all, I have 2 Epifani UL 112 cabinets that I power with a Little Mark II head. Some time ago one of the tweeters stopped working. I ordered another one from Nick at Epifani and installed it and it still didn't work. Well, I sort of let it go and relied on the tweeter from the other one. Just recently the other one went. Now I have no high end sizzle and I can't live without that. I recently pulled out one of the tweeters and replaced it with one from my SWR goliath Jr. cab and that one doesn't work either (and I know that one works in the Goliath) . I'm at a loss. I don't see a fuse anywhere on the back panel. Has anybody had this issue? Any help from the great minds on this site would be awesome!
