i hate to ask but I Really Need Help


I recently purchased a plinius 8200 and i am having a serious hum problem, not the kind that is bearable when the music is on, something is not right. To get to the point i am going to list all the facts that may be relevant and what i have done so far.
-i live in the south in a house that is 60 to 80 years old, i do not know anything about the wiring, i rent so any improvements to the system are out of the question.
-i switched the old two prong outlet to a three prong, i connected what appeared to be ground wires but i do not know if the are truly grounded.
-i have tried three sets of interconnects, different speaker cables, using cheater plugs, a RGPC 400, a PS ultimate oulet and different power cords in a number of different combinations to try and solve the problem which i have been sucessful in dealing with in past apartments.
-occasionally when trying different connection combos i have powered on the system and the hum is gone but if i change the volume by touching it sometimes comes back, sometimes it comes back with out being touched.
-HELP! i am completely unable to use my system at this time
i will try to promptly answer any questions that may help

I know a lot of homes(older) in the South did not use the regular three wire outlets with neutral, hot and ground. Instead they used the neutral as ground(there is no actual ground wire) I have run into problems actually grounding and/or installing stuff around here. Check the wire and see if it is 2 conductor Romex or if it has a metal shield on the outside going to your outlets. If it has the metal shield, you can use this as a ground.
Try(if you haven't already) rotating the plug 180 degrees on one component at a time and see if the hum will stop. I doubt you have the standard sockets with the large spade small spade opening unless they were upgraded at some point. You can use a cheater plug if need be. You may have a polarity problem with one piece of equipment.
Also, if you have any variable lighting---turn it off. It feeds back on the line in these homes.
Audiogon and its owners owe " da man " serious respect in my opinion as I frequent this site three times as much as I probably would otherwise if Sean were not doing his thing.
thanks for all the help, especially the post from Sean, i'll probably have to look it up in the future. Thee problem truned out to be something wrong with the cd inputs, i did not detect this the first time i checked them as they do not repond to movement (it does not affect the problem when they are wiggled) and they occasionally work leading me to believe the problem was elsewhere, however upon trying another set of inputs for last night and this morining i have not had problems since, once again i appreciate the help for all and once again thank you Sean for your time.
Mkaes: Glad that you were able to solve your problem and that it was a LOT simpler than what i suggested. What i discussed is a LOT of time and labor and i'm glad that you didn't have to go through all of that without planning for it. Having said that, this is something that really should be done if striving for optimum results. Between doing this and cleaning all of the connections within the system, the difference in the noise floor, dynamic range and liquidity can be staggering.

Other than that, i appreciate the words of support posted here and received in e-mail. The main reason that i take the time to do things like this is that i think that it may help others. That and the fact that i think that you folks are worth it : )

Hopefully, having a step by step guide to walk one through such things like this will encourage those that are "hands off" type of people to give it a try. It is not nearly as tough as you think, but it does take time and a plan. Now that you've got a plan, try to make the time. Maybe it will take longer then expected, and you might be without a system for a day or two ( possibly longer depending on your schedule ), but in the long run, you'll come out WAY ahead. On top of that, this will not only benefit the entire system equally, you'll have learned a TON along the way AND done so without spending a small fortune.

Besides the benefits that can be achieved, you'll come to understand just how much "small" tweaks can add up into major improvements. Just bare in mind that the result of doing all of this isn't necessarily an "additive" tweak i.e. MORE of everything. This is more of a "subtactive" tweak. That is, it removes a lot of the grain, glare and noise that you never realized that was there. By reducing these effects, you do get "more" detail, resolution, clarity, liquidity, "ease of presentatin", etc.. but it is not an "in your face" change. Rather than sounding "BIG" and "DYNAMIC" and jumping out at you in a "hi-fi" sort of way, you find yourself being drawn into the music rather than the presentation. While listening to the music, you find yourself not only tapping your toe, but marveling at the small sonic details and subtle changes that were never to be found before. That's because a lot of the artifacts of the gear itself i.e. self-generated noise within the system is no longer interfering with the music and what we hear. Call it a removal of "inner-conflict". Not only does the system sound more confident due to casting out the inner demons, it is no longer afraid to reveal the inner beauty that it had all along.

Try it. I'm not joking about the results. And clean those contacts while you've got it all pulled apart. Sean
