@@The718Motorpool Grew up in NYC. I heard ambulance sirens 24/7. NYC EMS went from the breadbox type ambulances which had mechanical sirens, to the very few bread boxes with electronic sirens. Then they went to type 1 ambulances, which they stayed with. The siren you displayed couldn’t have been in widespread use. I never heard it. EMS in the 70s got very little funding, very few new ambulances. The next widespread siren from the mechanical ones were the 2 tone hi-lo/yelp ones that became the standard before they went to a code 3 siren. I also worked for them for a year.
From the Advent of electronic sirens my favorite is the manual wind down I think it is the most effective and the FDNY used it exclusively
Old school was the best
this siren got real old it dont work anymore
I think if I had it running a few minutes and let it get warm. It would’ve worked a lot better.
Yeah these aren't electronic drivers for the sound these are old vacuum tube drivers
That was not the tones out of NYC EMS AMBULANCES in the 70s. There was no wail, just hi lo and a yelp.
From what a very reliable source from New York City EMS told me these were in the buses from 76 to 79
