Full power test of Leslie Tyfon 425

This is a full-power (140 PSI, 3 diaphragms) test of my Leslie Tyfon 425-DVE from the great lakes ore carrier Joseph Frantz. Framerate is low because my camcorder is in “night mode“. I’m very satisfied with the 120 gallon tank for demonstrating this horn. After all the toots you hear here, plus a few more after the recording ends, the tank was down from 140 to 70 psig. Over this range of pressure, the tone and pitch of the horn did not change appreciably. Comments related to flatulence will not be app
