    I got a 6 volt pair of 1940 Plymouth trumpet horns to work but dong so messed up the sound..

    I thought or read somewhere one is E Flat the other is C ...?

    Which one is which one is shorter than the other..

    I Tried to google a sound (cheat sound ) but could not find one (not much info out there on the subject)

    Does any one know which note goes to which one and have a demo sound to adjust them to Thanks
     
  2. Like a pipe organ, the shorter one will be the higher note.

    You adjust them until they have a clear , clean note. You can't adjust the pitch, just the quality. Set screw on the back, under the bell cover.

    Don't do it inside.

    Short update I spent around 4 hours but I got the horn (I was working on ) to work as it should..

    Seems the point adjustment is not much help The problem was the round 2 inch disk .. IT was out of adjustment it was too close to the magnet field..

    Once I reset the gap by loosing (the hold down nut) it up , and making a larger gap,, IT made a clear note...

    There is no way too adjust the horn for a different tone..

    The Point are adjusted too just touch and once its energized it works like a diving board and springs (fast) opening and closing ) making it vibrate..

    I usually adjust modern horns with the set screw and makes different sound not these. These have a metal diapram and are preset...

    I think my Autolite horns 1940 are E flat and G

    The notes should clash, making the sound of the horn more noticable, hence the two tones.

    You did it right. The set screw is what I was referring to.
