Guys,

Thanks for your comments on this. I am going to make an effort to try a true ground in the next few days with a few different sets and see what kind of difference (if any) takes place.

I certainly want to try a true ground with the 1935 Philco cathedral I recently bought. It has fresh electrolytics and caps in it, but still produces a noticeable hum. It makes me curious if the ground being connected would take away some of the hum.
