Skip Goulet said:Another note about the doubletones: we had a rebuilt 77GBD (specially built demountable model [have you seen one, Tim?]) on the '60 Chevy station wagon ambulance operated by our small standby ambulance service in Lubbock. We "inherited" the siren when the local racetrack owner gave us the old wagon following the large tornado that had hit Lubbock in May, 1970. Prior to that we had used the old wagon when working standy for the track, but at that time the old wagon only had a short-skirted Model 17 beacon on top and the siren had been removed. As it turns out, the siren had been rebuilt locally by a local starter/generator shop (that makes Kevin O'Connell cringe when he hears that), so I'm not sure what sort of motor it was; but it was definitely not a siren motor. Because of the slight mismatch we couldn't run the siren with the clutch set to allow the siren to coast properly, and we found that out the hard way. If you ran the siren up, like clearing an intersection, and then allowed it to coast but then had to roll it over again, you could hear the motor winding but it wouldn't engage the rotor. So we ended up tightening the big nut on the clutch all the way down, thus making it basically like a doubletoned-66; but it would wind up and down properly that way.
However, with that motor being a bit ovesized it really made that siren louder than anything you could imagine. One of our guys worked as a projectionist at a move theater at the corner of 50th and Indiana in Lubbock. Indiana was the thoroughfare we used to get to the hospital when we came in from the track. One night he had had to work late and happened to be in the lobby as we were coming up Indiana on a run. There were a lot of kids in the lobby at the moment, and he said that when we peaked the siren it literally rattled the plate glass windows in the theater! And he said that he heard more ooohs and ahhs from those kids then from the action-shots in the movie that had been playing!

Night Patrolman said:Actually, I read somewhere on this site that the US Secret Service or some other government agency ran a special variant of the 70 Series that was a direct-drive siren like the 60 Series rather than a coaster. Don't know much else about those, though.
