ACA was a subsidiary of the Biersach & Niedermeyer Company. Biersach & Niedermeyer filed for bankruptcy in November 1992. B&N sold ACA to Hormann GmbH who then renamed it American Signal Corporation. Then ASC was bought by Dale Moeller in 1999.

You can get 100-W drivers off the shelf, you can get those rotators off the shelf. The only place you are right is if there was a controller problem, but the controller ASC used up until the NexGen CompuLert was essentially the same as what they put together during the mid-90s.
In regards to the rotating Alertronics, there are some parts you can't buy off the shelf. Controls, rotator platform base, and fiberglass horn casting. ACA and ASC would have offered such parts in the past, but that's not the case anymore since they don't support the older electronic sirens.
I've never seen a successful electronic siren restoration. A case in point would be Rock Spring's Alertronic which itself was compiled from 6 different Alertronic sirens' parts, yet it still does not work effectively. With the decidedly-short lifespan of an electronic siren in mind, it's just not worth the bother even if you could pull off such a restoration. It's easier to just replace the siren.
