Elmo magnetic sound roller replacement

This video covers the installation of the magnetic sound roller on Elmo 16mm sound projectors. It shows the install procedure for the Elmo CL, Elmo ETC, and Elmo TRV. The Elmo AL and Xenon machines are a slightly different in design, but this video should be useful installing a magnetic roller on these models. Not all Elmo 16mm projectors have the magnetic sound option. Many Elmo 16mm projectors are optical sound only.
