I don't see the use in conditioning the line, but have been toying with a UPS battery backup to allow the various fans to run for a bit when the power dies. I know (read: "I read somewhere") on Rear Pro TVs not running the fan to cool the bulb can cause some issues. Figure it can't help amps either.
