Good Day Just got off the phone with Klipsch. I have a pair of KP-250-A Serial# 004392568 Professional Speakers. One has no audio coming out and has a missing fuse & fuse holder (Non-working speaker doesn't have fuse & fuse holder must have fallen out). Tried feeding signal from working speaker & putting fuse from working speaker in non working speaker. Unfortunately there was no change (no audio). They have been stored indoors for awhile and haven’t been used. There Appears to be some kind of corrosion on black/red terminals. Thoughts? I have never had these speakers totally not work for any reason. Can crossover still be purchased & does it have a part#? Would appreciate any input that can be provided. BTW: I have new old stock of the tweeter, midrange & woofer. Thanks Jeffrey
