Hi,
I have an 100W stereo amp with one broken ground connection. I would like to know if I can simply use the one good ground connection for both my left and right speakers without causing a sound issue? I just want to be sure before I ruin something. My other thought is to use a case screw for a ground?

Thanks in advance for your help.

Likely not a good idea. Often times the "ground" speaker lead in solid state amplifiers are not true grounds but are separate reference/return for each channel. A make and model and/or schematic would definitely help here.

Suncalc,
Thank you for your reply. I did some google research and I did find some info regarding this and It was all basically what you said.
I got a brain storm and I was able to take off the cover, however I was not able to see much there. So I got to looking at it, and it is the spring loaded snap type connector. Because its nothing fancy I got my dremal out and cut the plastic around the metal tab. With that now exposed I turned on some tunes and with a very low volume I had the good pos wire in tight and I simply touched the now exposed metal with the bare ground wire and it all sounded great. For kicks I touched the ground to the case and it did not have the power compared to the correct connection.

So now I will just solder a piece of wire on to the tab and secure it to the case and it should be fine for a while. Thanks for the advise, you were very helpful and finally got off my ass and im getting it fixed now.

Thank you!
