M-Audio AV40 loudspeakers (faulty) (N12 North Finchley)

This pair of M-Audio AV40 loudspeakers suddenly stopped working and now make a loud buzzing sound. If you'd like to have a go at fixing them or have a tatty pair to do a two-into-one job they are really nice small speakers. Far better sound than most speakers sold for use with PCs. Please give your phone number and say when you can collect. I am in North Finchley, N12.
