Photomultiplier Tubes (PMTs) are robust and cost-effective devices for detecting the weak light produced by subatomic particles passing through matter. They serve the dual purpose of converting light into an electrical signal via the photoelectric effect and amplifying this electrical signal for further processing. This amplification occurs in stages (typically 10-12 stages), each stage at a slightly higher electrical potential than the previous. Resistive voltage divider arrays are used to provide these potentials. The JMU Particle and Nuclear Physics group designed, built, and is currently assembling and testing ~1100 voltage dividers for the electromagnetic calorimeter ECAL which will operate in Hall A at Jefferson Lab as part of a group of experiments aimed at measuring the electric and magnetic form factor of the proton and neutron. This presentation documents the final assembly of the ECAL voltage dividers (mechanical attachment of the electronics board to the PMT socket/cookie, wiring of the amplification stages, and attachment of the high voltage and signal cables).
