ChrisM Posted September 2, 2019 Report Share Posted September 2, 2019 I am about to start working on my IIIs. They are in essentially untouched, lovely condition. They are circa 1970’s models. I also have some butchered IIIs which are also lovely but all the drivers except the Flexair woofer were swapped out for cheap Radio Shack drivers. They basically wrecked the front panel putting in the RS parts so it will get replaced. I have the correct midranges and some little cone tweeters which might work. I am also considering just putting in one modern dome tweeter. So in the course of this, I noticed that the Flexairs’ surrounds are a bit dry. I called the folks at Great Plains Audio because the Flexairs are relatives of the mighty Altec 15’s (which I also have) to ask about buying appropriate goop for accordion surrounds. Short answer, they don’t have any. If an Altec dries up it would get reconed. Their new cloned drivers use a PVA compound which can’t be used over the old stuff. This brings me to a question. Is there any way to get a larger quantity of RoyC’s magic elixir without paying a fortune? I also have a bunch of other old drivers which need some rejuvenation. I suspect the reason it is expensive is that because as far as I can determine the minimum quantity of liquid butyl rubber is 100lbs. Not cheap. I’m not opposed to mixing up some myself but I can’t find smaller quantities of the butyl. Toluene is easy and available in gallon cans. Any Ideas?
