60 cycle hum


I'm running a Rega P5 with outboard PSU into a Yamaha receiver with an internal phono stage. I hear no extraneous noise with the needle off the record 'til the volume control hits 12:00 - it then increases as the volume increases.

Playing records, the Exact cartridge has such a high output that I routinely listen between 9:00 and 10:00 and get plenty of volume...

Is the hum a problem or am I looking for an excuse to buy an add on phono stage?

BTW I seem to recall the same "problem" with an old HK receiver and a Denon TT with a Grado cart........but I thought it was Grado hum and when I swapped the cartridge for an Ortofon it was still there, but only at very high, not listening, volumes.

any comments would be appreciated.

Additional information: hum present in both channels (speakers). Becomes louder as tonearm approaches the spindle. Hum disappears when phono leads disconnected from receiver. Doesn't seem to vary when leads moved away from/toward power cords behind receiver.
PSU is located about a foot to the right of the TT. I've tried reversing its plug polarity and plugging it directly into the wall instead of the monster HTS 2000.
Thanks, Vinyladct..........it is well below any level I could stand. If I get it too loud my parrot screams - he wants me to save my hearing. (and his)

The reason I bought the Rega in the first place is set it and forget it operation.

I can even tell in the next room if it's a cd or an lp playing.................and those .50 and dollar finds!

Thanks everyone for input and help.
