your luxman is up to NEC standards I assure you, it is internally grounded. You don't have to have an equipment ground to be NEC approved.
Ground Loop?
I seem to have a ground issue with my phono preamp a Parasound JC3 Jr that just started about 3 months ago. I've tried very thing. A different Preamp (Moon 350p) replaced an Emotiva XMC-1 Different TT but still has the issue whether it's connected or not. I have 2 dedicated 20 Amp lines direct to fuse box and plugged them directly into the sockets bypassing my conditioner Audiance V8. It's a tapping sound with static but when I touch the loading pot in back it stops chattering but has a low-level hum. I have even sent it directly to Parasound and no issues were found. Going nuts!
