This is the 3/9 Barton theater pipe organ, located in the Al Ringling Theater in Baraboo, Wisconsin.
We have been making repairs to the organ, beginning with rebuilding the wind pressure regulators. Our next round of repairs will be to rebuild the tremolos, which give the vibrato effect to the sound of the organ. This video was made after a long day, of making repairs to the wind system, and bracing up the pipe racks, plus a thorough tuning of the organ.
