Edge Electronics ACF-1 in excellent condition. I have two units that remove DC from the AC line and only need one - this is the much nicer looking piece of the two with more outlets. $350 OBO (MSRP $800) Here's a blurb from Edge:
" Edge Electronics' ACF-1 line filter helps to solve one of the biggest problems in some audio/video systems. Specifically, it conquers the presence of unwanted radio frequency (RF) and direct current (DC) in your home's electric supply. Since most audio equipment is power by a toroidal transformer of some kind, it is very important that the AC line be free of any DC. According to Edge Electronics, "0.1 volts of DC present on the AC line will have adverse effects on the power transformer. We have tested a 1000 VA transformer by introducing 0.1 volt DC to the AC line... and idle current rose to .95 Amps! That is 12 watts versus 114 watts at idle which translates into an almost 10 fold increase in power consumption." In addition, physical noise went from -86dB to -65dB. The ACF-1 line filter addressed these issues.
Buyer pays actual charges for shipping of choice - shouldn't be much since the Edge is pretty light for its size. I ship within 24 hours for Postal Money Order or Paypal (buyer please add 3%). Checks and other money orders are fine, but need to clear my bank before shipping. Thanks for looking!
