Zaikesman: I have done some pretty heavy experimentation with a number of stock receptacles. I have a couple of Arrow Hart 8200's here (which have been hacked up a bit to fit properly in my line conditioner but are mechanically fine) and would be happy to send you one to experiment with. E-mail me your address if you're interested. I am no longer using these obviously, but feel that they are a pretty decent receptacle, but not as good as the Hubbell 52-53 series or 82-83 models. I am currently using the cryoed World Power 5362's, both at the wall and in my line conditioner and would not be without them. For $55, they are, in my opinion, an absolute bargain. FWIW, I was as skeptical as you and now have numerous receptacles about the house: my washer and gas dryer are running off an Arrow Hart 8200, and my refigerator, as well as downstairs freezer are running off Pass and Seymour 5262's and 5242's. In any event, I'm happy to send you the AH as I am confident that it will be better than what you have (if not, send it back to me!) and may lead you on to better things.
Regards
Blake
