Lawrence Phelps & Associates, A Corporation for Organbuilding

The Phelps Organ at Christ Chapel, Oral Roberts University

Move your mouse over the film strip to see the enlarged picture!

When the first picture is showing, place your mouse over the picture to see what the different divisions of the organ are!

This organ was the largest mechanical action organ built in the United States at the time it was installed. There was also a Wurlitzer Theatre Organ behind the grille off to the sides. The theatre organ console could play both organs because the main mechanical action instrument also had electric action capabilities. The theatre organ has since been sold and removed.
