Upgrade 20 years old crossovers

My last thread informed me that the best thing I can do for my great 20 year old speakers is replace speaker wire inside cabinet and replace capacitors etc. on the cross over circuit board. Please help me prioritize in what order to change components on an old cross over circuit board say electrolytes, plate capacitors, resistors etc. Obviously there is diminishing return. Thanks in advance for helping out.

Dcaudio, what did you decide to do? Did you upgrade anything?

i upgraded my B&W crossovers and it did a lot for those speakers. YMMV.

I have Dunlavy SC-V's. Although I wanted to get the crossovers modded using Duelund parts, I decided not to proceed after inspecting those big crossovers. The speakers are 4-way with seven(!) drivers in a d'Appolito configuration, so you have to have large and complicated crossovers. To remove them from the speakers and ship them for modification is a bit troublesome, so at the end I kept them in place. I think that if I had 2- or 3-way speakers with less drivers, I would go for the modification. If you want to see some pictures of the crossovers, these are the links:
