Mark the back of the cover where handy access hole should be. Take the case cover to another area (i.e. away from the exposed CRT neck). Remove the control assembly from the right side of the case. Using a Dremel tool, hole saw, … cut an approx. 1″ diameter hole in the back of the case. Use this opportunity to give the case interior a good cleaning.
