Retensioning electrostatic panels is required for most models over time in my experience. I learned the technique in '77 from Jim Strickland, the father of Acoustat. And periodically treat both the Sound Lab stats upstairs and the Acoustats in the HT.
I use a hair dryer but the key is moving across the diaphragm and not "torching" any one area. Definitely helps when the surface is visible as it is easy to see when any wrinkles are gone. You can always practice using window insulation which works the same way. We live in an older house and the glass that frames the front door is decorative but not double insulated. I covered them with plastic film and used the same dryer technique to pull that diaphragm taut for best insulation.
Sorry, I'm not anywhere close to you.

Hi Ralph, this is Blair Gardner. You were very helpful 3 years ago when I was looking to buy Soundlab U790's from Brian Walsh. I always wanted to try a pair of the ESL-63's but they aren't quite in the realm of the Soundlab or Acoustats. I sold the U790's and still have Acoustat model 6's, 2+2's, 1+1's and a pair of model 3's. Thanks again for your reply.
I had the good fortune of meeting him a couple of years ago while on business in KC. He had just finished rebuilding some 57s and we enjoyed an evening of barbeque and listening with his ARC gear.
While the 57s powered by a REF75 didn't have the scale of the 790s, they sure sounded nice. Should you send your 63s to him, they will be in good hands. Some time ago, he had a modified pair with additional panels adding height.
I remember your story, Blair. See you're still solidly in the Acoustat court! What happened with Brian's speakers?
Wifey and I did a home improvement project coring the center of our house combining the kitchen and family room spaces for a much more open approach. We were in construction for more than a year but the results were well worth the effort. The 1+1s cum subs (placed at opposite sides and ends of the room) and Maggie MC1 surrounds work great there. Another goal to minimize the wire jungle so I specified having conduits run in the wall and under the floor along with a hidden closet to house some of the gear.
