I vaguely remember either being told this or deciding this too.

Is there a chance that this thing could emit a low hum that's picked up by my pro audio gear during recording sessions? The floor of the studio is directly above the ceiling of the garage. And I've had an everpresent faint hum at approx 60 cycles that I keep having to deal with.
