my first 2009 find - 1988 Magnadyne

[Kiwick]

Damn! i took the speakers out of the set to blow 20 years worth of dust from behind the metal grilles and noticed the foam surrounds on the oval woofers are perished, they're still there but they have a few radial cracks and some kind of mildew growing onto them, i think they're getting brittle and they will probably disintegrate if i keep on using the set.

The speakers are two way coaxial units and they put out one heck of a sound, i doubt a replacement will sound as good.

Is there some way to repair and preserve the original surrounds, like brushing some kind of glue onto them? or any place on the Internet where i can buy replacement oval foam surrounds? they're absolutely unobtanium around here.
