Re: Production Intercom out of business
Ahhh.... history repeats.
A long, long time ago there was a company called Technical Projects, based in the Isle of Wight, who designed an intercom system. The licenced the rights for USA manufacture and sales to Production Intercom Inc, though I don't think they were called that back then. About the only change from the original was the replacement of the incandescent call light with an LED. By this time the beltpacks, the AD903, the master stations and power supplies, all that stuff was designed and in production in the Isle of Wight, and Production Intercom brought that whole range to the USA marketplace.
Pictures of the old TecPro stuff here:

Then, still many years ago, the original Technical Projects in the Isle of Wight hit the wall. The the remains and intellectual property was bought by
Canford Audio, a sort of UK equivalent of Full Compass, and they've been selling compatibles spares and intercom units for many years under the TecPro name, see
here. They also sell many other compatible and competitive systems "alongside".
I was about to say that I don't think they've done anything with the brand since, just cranked out the original design, but they have a new range of beltpacks, very different in look to the old black boxes, and they've updated several other bits of kit.
