Lyra Lydian Beta, Rega hum?


Just mounted a Lyra Lydian Beta on my Rega P25/RB600. Got some serious hum. I have heard of problems like this with Grado cartridges, but not with Lyra. Does anyone have experiance with this combination? Phono preamp is Sonic frontiers SFP-1.

WOW!! Who woulda thunk it?!? Thanks for the update- I was wondering how this would turn out...

Jsbail- At the risk of stating the obvious, do you have a good ground? Have you tried it w/o a ground?

Are you axperiencing hum all the time or just when a record is playing? Is the hum from both channels or just one? Could you provide more specific details?

Have you inspected the wire clips to ensure that there is good contact with the cartridge pins as well as a good soldered connection to the wires? Are you asdsolutely sure that each wire is connected to the correct pin?

Jsbail- A constant hum such as you are describing is most probably some sort of grounding/misconnection problem as it is happening with both cartridges. I used to have a P3 and recall that there is some way to ground it, but I can't recall exactly. I think it had something to do with connecting a wire to the arm at the attacment point underneath the table and then to ground, but I can't be sure. Sorry.

Anybody out there know about grounding a Rega? Maybe the Basis Brothers could describe how their RB300 is grounded?

The only other thing I can add is that I once had a similar problem and it turned out to be a wire not soldered well to the connector pin.
Jfreck is correct that the Regas ground through the RCA connectors, but I do recall somewhere that this sometimes is not adequate. Perhaps certain pre's and/or phono pre's need additional grounding as Jfreck suggests.

Perhaps you can locate another table (non-Rega)to borrow and see if the problem persists?
