Lyra Lydian Beta, Rega hum?

I did a little troubleshooting today. I hooked the Rega/ Lydian up to an old Yamaha A700 integrated I had in the attic. The A700 has an MC phono stage. At first there was only a very low level hum. Then I realized I had the A700 in mono mode. Switched to stereo. Big hum. So I put the Rega/Lydian back in the main system and tried mono; low level hum. Switch to stereo; big hum. Did I get a bad cartridge? Or is the cartridge picking up the hum from some other source? I am just getting back into vinyl and am not having fun yet. Please help me before I bail (excuse the pun) 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?

I have a Lydian Beta with a rega p25/rb600. Bat pre and phono stage. No hum at all. Got to be something you can troubleshoot such as Jim's advice above. Also, maybe a defective cartridge?

Also, I'm curious what you think of the TT/cart combo. Sounds lean to me...not a lot of body...bass is great and soundstaging is great. maybe my cardtridge loading is off or VTA-since it's fixed?

The only thing that left for you to do is to contact Immedia and report that problem. It might be a problem with cartridge internal wiring.
BTW Rega turntable is a big compromise for Lyra but it shouldn't hum. Lyra can deliver much more from the Basis 1400. Basis 1400/RB300 combo will definitely smoke your current analogue setup.

The P-25 isnt causing the hum.
The Basis 1400 does not 'smoke' the P-25
I listened to both before buying the P-25
The Basis is better for light classical and Jazz but the P-25 SMOKES the little 1400 with good old rock and roll! All depends what you want from a table.
