Attached to the incoming from power plug negative and to the chassis? I took this out and put a copper wire in, on my Rotel. The amp simply sounds better now with the new cord and new "ground?" wire. The part of the chassis holds the transformer and some large capacitors. I had no idea I removed a resistor until after I was playing around with the fickle thing.

The resistance on it is 2.2 million with 10% tolerance.....

My receiver sounds much better now, rather big difference, and my soldering is better then what it had before, I am the solder master   .

I can hear the musicians voice much better, much clearer, and the lower frequencies are a lot better. That kick bass drum rocks now.

This is a grounding thingy, and I'm not even going to try to explain it. Just try and remember that there are no grounding standards in consumer audio and just about anything that can happen, usually does happen.

What else is grounded to the chassis?  Is that the only ground wire?  The resistor is a "network" used to send junk to the "ground".  On the DIY Audio forum, there was a post that included an excellent description of grounding (in this case, for equipment with digital and analog sections), but I cannot find it right now.

I some what figured it out... Basically it prevents noise from being dumped or grounded through certain pots, and then into the ampification. I do not really know the whole deal, but basically if I move the bass knob when I first turn it on, with no music, I will hear a bit of noise, but it bleeds off when it is turned on.

Hm oh well it sounds much better now.
