The tape certainly won't cause any harm, but there were
tens of thousands, and still are hundreds of these scopes that
never suffered this failure on their own.

My guess is someone got aggressive with the wire, and tugged
it hard, which caused the resistor to rotate into the chassis.

Good job in finding the problem.

I would think that a better way would be to properly align
the resistor so that it is away from the chassis. It got
bumped.

I did. The electrical tape is just to stop it from happening again if it loosens.
