jea48 and anyone else who'd like to chime in, As of late my wife's blow dryer is causing my Topaz 1.8Kv line noise suppressor transformer itself to hum loudly. From what I have read, DC is the most likely cause for these types of transformers to hum. Is there a DC blocking device/filter that I can put in-line, between the AC supplying the transformer and the transformer itself, to keep it from humming and without causing any ill effects to the sound quality of my system? If so, what specifically and from whom? Your take on the situation would be most appreciated.
