Hi, new to this to - be patient! One of my Celestion F30's has lost mid-range, by substitution I have worked out that the problem lies in the cross-over, which has just 5 components, 3 coils and two caps, a 9uf 50v and a 10uf 100v which bridges the MF output. My question is would the most likely failure be one of the caps? and could I replace the 9uf with a 10uf? I'm guessing the coils would be almost impossible to replace (.85mh & 6mh) as Celestion don't seem to exist as far as domestic speakers are concerned. Thanks in advance for any help.
