Saw "tacky surrround dampener" on ebay from Springfield Speaker Repair, so I wrote the owner for more info and he assures me that it is the original solvent-based vinyl acetate Altec goop.

quote:

"Professional-Grade vinyl acetate-based tacky surround dampener and adhesive specially formulated for attaching and dampening cloth speaker surrounds. Commonly used on older Altec and JBL speakers among many others. Product is also extremely resistant to water Goes on white/tan; but dries clear and shiny, and REMAINS TACKY. Looks amost brown with age. This is the REAL THING!!"
