Hi Jason,
Wow...sorry to hear...and lots in your description to 'chase down'. Lets start with the basics...discconect the turntable. there is lots that can happen there we should isolate. Does the system still have weak signal and feedback without being hooked up to the turntable or the turntable even being plugged in? (ie, thru the DVD player)?
If you turn the DVD player off, and just have the preamp and amp on...do you stll get feedback/static? If yes, then it is somewhere in your preamp or amp. Turn your system off...turn back on just the amp. Still any static? If not, it could be the pre or the cable inbetween pre and amp. If yes, it could be the amp...or the wiring in your house.
If you can try to do a few of these 'easier' isolations tests...and post them back, maybe some of us can help.
good luck.
