Rega hum

How far away is the pre from the power? The preamp phono section could be picking up hum from a nearby transformer.

Hello Miner42:
I had a P3 that had the same problem. Rega's response was the same. When the LP is playing there is much less hum. I was using a Jolida JD-9 phone stage (tubes) and I found with an upgraded power cord (LAT International AC-2) the hum was much less. I also noticed that once I gave up on trying to get rid of it, it mostly went away. Perhaps one of those audio mysteries like cable break-in. Once everything settled in it was much better. I'm using a Rega RB1000 arm on an LP12 with a Graham Slee Reflex phone pre and it's dead quiet. Maybe the upgraded cables in the RB1000 make a difference or maybe it's the preamp.

Have a little patience and perhaps it will improve.

My Pre is one shelf above my power amp - a Rotel RB-1092 - about 2.5" from top of power amp to bottom of pre separated by .75" of oak.

Arch7,
If I were to upgrade my power cord should I upgrade the pre or the amp power cord? The power cord to my TT PSU is not detachable.

Thanks to all who have submitted their opinion.

Miner42, try moving the pre away from the power, 2.5 inches is not very far, the oak shelf makes no difference. The phono section of the pre is probably right above the power transformer in the amp.

Hello Miner42:

If you upgrade the power cord start with the preamp. Do you have a local dealer? They should lend you a cord or 2 to try, hopefully ones that are broken-in. You would hear immediately if it makes a difference or not with the hum. Whether or not it helps the hum it should improve your overall sound especially if you're using a stock cord now. Then the can of worms if officially open. Power conditioner? Upgraded power outlet in the wall. Dedicated circuits. Nuclear reactor in the basement.... it's endless.
