Rega hum

Rotel RC-1090 pre
Rotel RB-1092 amp
Rega P5, TT PSU, Exact cartridge.

Noticed this weekend an annoying hum in the background especially with nothing playing on the TT and volume up. What do I need to do to rid this hum? I realize Regas are grounded internally. BTW, table is completely stock. All equipment is plugged into a Rotel RC-1040 power conditioner. Thanks for all suggestion.

Then you might be back to trying an upgraded power cord.

Which power cord should I upgrade? The Pre? My TT has its own PSU. I did find that if I did not have the TT PSU plugged into the swithced outlet on my pre the hum diminished somewhat. It (TT PSU) is now plugged directly into a wall outlet. This may be as good as it gets since I can not locate my equipment from ther current locale.

Try eliminating the power conditioner. I've never met one that hasn't caused some problem or other
