I would call them, give them the unit's serial number and let them know the history as well as your current static challenges. If a unit has had a few owners I know I would send it in for my own piece of mind. The lifetime warranty, if available, is a useful tool as well. There are capacitors that will wear out at some point. Might as well see if you can get covered. No harm checking.
