[ARC5] Removing plug retaining rings

[Matt P]

....and the results are in; ring has been removed. It might not be pretty,
but I was able to break it free this evening with channel-lock pliers.
Before attempting, I unscrewed the junction box assembly from the tray and
worked the audio wires a bit so that I could pull the tube out. Then I held
the box down firmly on a sheet of rubber gasket material on the edge of the
workbench with the rest of the tray laying down next to it; (there was just
enough slack in the audio wires running through the tube). It wasn't easy
at first, felt like it was held in place with a gummy material but couldn't
actually see anything. The more I unscrewed it, the easier it got.
The ring has a fre "extra" grooves in it, but lives to see another day if I
should need it again. Perhaps the Evap-O-Rust loosened up the corrosion
just enough.
