In Reply to: RE: jea48 DC on the line to isolation transformer causing hum? posted by Duster on January 30, 2017 at 13:52:01
Why couldn't the blocker be installed between the hair dryer and the mains wall receptacle? I think it would work the same and block the DC from the hair dryer from going back out on the AC mains.
That seems like a brilliant solution, jea48. The same notion as implementing any kind of AC power line filter effort firstly on the noisy appliance rather than only trying to block audible noise just before the sensitive component involved. Sometimes, audiophile filtering can be effective at both ends of the situation. I'm not an EE, so maybe Jon Risch could post his insights.
Me too and one on the microwave as well, just for grins.
I love the Hum dinger by AVA. Doesn't seem to harm sonics that I can tell. Without it my power conditioner hums like crazy.
