It's suspicious because it forces the experimenters to use a specific line in the room. It's also suspicious because it supplies a much higher power, and that may have been necessary in the run where the ceramic melted. And regardless of how long it's been around, it is more difficult to measure power than from a simple single-stage ac input. Why complicate things unnecessarily, if not to slip a little deception past some credulous scientists?
