RE: Odd hum issue - suggestions ??

I don't know what those upgrades are. Is this a new problem in this preamp, or did you buy it like this?

"Sure enough, the ground lead was secured at one of the inside foot screws."

Do you mean the green wire from the line cord? If that's connected to the chassis, touching the chassis should have no effect. This might be a problem with your house wiring.
