KEF 104/2 rebuild

Hello 'Goners-

I've just come across an old pair of single-wire KEF 104/2 in pretty good shape, and have read that they can benefit from a rebuild, i.e., new wiring, crossover work, replacement of tweeters, etc.

The woofer surrounds and "doughnuts" seem to be in good condition, so there's no need to redo them at this time.

I'd like to correspond with someone who's done a complete rebuild, or someone who can tell me where to access step-by-step "how-to" documentation.

Any ideas?

Thanks,
Bob R
