Advice needed for Refurbishing AR-2ax

[shacky]

Sorry - I meant rubber cement ! But I might try some of Joe's examples in future. I did feel it took some time for my cloth surround to "break in" after using the rubber cement.

I would lean a little more toward Joe's method if I could not find the original compound used (I think you can still get something similar - maybe MacAltec had some? Might be worth a PM...). And I would think anything applied to the surrounds would require a break-in period, even the thinned latex.

Back under the hood...

Well, I went back in to the AR2ax tonight. Removed most of crossover stuff so i could get at the pots. I've attached a picture demonstrating the method I used to pull those speakers. Also, there are some close up images of the pots and one of the sliders that is eaten away. I need some ideas for fixing that. It may be too far gone...

Thanks to all for the parts offers... I still need to crack open the other speaker to see what condition those pots are in.. Perhaps tonight or Sat...

i rebuilt a pair of ar2ax's a couple of years ago, i paid put $60 into them (new caps, new surrounds(later models had foam surrounds) and new attenuators). i sold them 6 weeks ago for $125 to a woman who wanted to sell me her stereo equipment but i changed her mind. she needed some help with her turntable last week so i stopped by, walked in the house and i heard them, they sounded wonderful ! they have a beautiful musical quality about them and i was happy to hear them again. there is a guy named larry that sells ar stuff on ebay. i don't know how many attenuators you need , but i have two that when tested read 0-14 ohms . pm me if you are interested.

Found a perfect cloth surround coating for the ARs

I found the perfect stuff to recoat the vintage cloth AR surrounds. It's called "Good Bye Cracks", an rubberized elastic crack cover for spraying over small cracks in walls. It sprays on, dries like rubber, but isn't sticky. Perfect and easy to apply. I found it on the paint/caulk isle at Lowes. See pic.

Pics of the newly coated surrounds

It looks good doesn't it? Note one of the pics is before the treatment...

Look in the side view photo how the surround is standing tall again. Also very flexibe. Can't wait to get this one back together with new caps and new pots. I'm gonna wait an do the other one after this one is finished so I can compare the way they sound befor and after.

Did you spray on - or brush on? Looks like brand new surround! Looking forward to your before/after comparison.

I sprayed it on. I cut a circular piece of cardboard to cover the speaker cone, and I masked off the outside edge with blue painters tape. Sprayed two coats about 30 minutes apart.
