Well I finally got around to recording the Redfield Thunderbolt 1003.
After many requests (urrrrgh) I decided to hit up the 1003, a 1004 and get a audio recording with my micro-recorder.

The siren was supposed to sound at 6:00 PM but they had a delay, I contacted the fire department and a firemen who was responding to me said they were having to set up for the meeting and that they would be sounding the sirens at 6:30.
I waited and at 6:15 they sounded the sirens, This Thunderbolt (1978) has a FC on it and no it didn't mess with the wail signal they set it that way on purpose when the installed this Thunderbolt.

It really made me jump :lol: and it rumbled my body and the ground as well.

The Mod 1004 up at the behavioral school did go off but they had a 3T22 that over powered it, as for the recording, they had to replace the original Mod 1004 head with a Modulator II 1004B head with a MC, I think a speaker driver broke halfway through as you can hear a squeal on it.
