I have a pair of Altec Lansing 872a Madeira speakers that I bought new in 1969 that have been stored away for a couple of years. They were stored grills against the wall but the live in cat decided to WIZ on one side of each of them. The bases that are attached to bottom are starting to de-laminate and the particle board is crumbling about 1" up. I've pulled the speakers out and had them checked out & their A-ok. My question is would it be worthwhile to have the speakers restored by a cabinet maker or just ditch them?
