If the foam surrounds haven't been done (as per Sdecker's post), check out http://www.simplyspeakers.com/
They can do them for you, or if you're willing to try it yourself (not for the squeamish), you can buy a kit. The BA "A" series were infamous for surround rot. I've refoamed an old pair of A60s I've had since the mid-80's, and it makes a huge difference.
Then again, I'm not of the opinion these qualify as "classics", just good speakers from the mid 80's that are worth a surround-job.
