Is it at all possible to replace a 3 phase 3T22 motor with a single phase one? If not, can it be converted to single phase?

When I was restoring my Model 28, I went to my nearest fire station to ask if they knew of such a place. They didn't. But its worth a try. If anyone knows, it would be them; and besides, firemen are usually quite friendly. And if that doesnt work, you can always replace the motor. I am sure that Gra...

I bet 99% of all the reports for broken sirens are from siren enthusiasts. Its funny how no one else would be able to tell just by hearing the unit go off that it is not working 100% correctly.

thankyou!

I have a few questions about Federal's navy klaxons. I saw on the H8 and H9 horns there was a "tuning screw" on the back of them. What does that do? The Federal IC/H8S4 does not have this tuning screw, and if the tuning screw is for what i think it is (volume adjustment), how do you adjust...
