Karl Wilhelm, Inc., Mont St-Hilaire, Quebec, has built a new
organ for St. Athanasius Church, Evanston, Illinois. The firm’s Opus 147
was built according to classical principles. Key action is mechanical, stop
action is electric with 32 levels of solid-state memory. Great and Swell
divisions are housed in the right case, Pedal division in the left case. The
two cases are made of solid white oak and designed to complement the front
altar. Pipe shades are carved from butternut wood. The tonal design mainly represents
the classic German and French traditions. Temperament is after Vallotti, which
yields five pure fifths. Façade pipes are of 75% polished tin. Other
metal pipes are of 32% tin and 68% hammered lead. The organ has two
wedge-shaped bellows, creating a flexible wind. Manual/pedal compass is 56/32;
25 stops, 1,600 pipes.
