NO MORE HUMMING BUZZING AT ALL!

I am using this Furman 215A power conditioner and was surprised at the results. All background humming buzzing over the air is gone completely. Any line voltage/surge over 130 VAC and it shuts down and surge protection is non compromising, not just a couple of MOVs  that degrade with each surge. Well worth considering. I've included pictures, serious electronics inside. This is not the same as a cheap surge protected power bar. Highly recommended. Vary favorable reviews on Amazon CAN and Amazon USA. Worked much better than I expected.
