To discover how the original relay and coupler components
were designed to operate, the main junction board had to be analyzed. To
help with electrical chores, two students from the Electrical Engineering
Department, University of Missouri were hired. Pictured here is Eric
Spoor. Eric knew nothing about pipes organs when hired, but he was
not intimidated. He viewed the junction board as "just another bunch of wires".
The main junction, on the right, has been replaced using telephone style punch down connectors.
The board on the left contains a series of ladder switches that couple
harp, chimes, and echo to various divisions. Over 26 miles of
new wiring was used in the restoration of Opus 1280.
