Somehow I've got myself a "WTF" dilema with my newly setup Turntable. HELP!

If I plug one IC from the "high out" of my phono stage (for example, the right side)
into the right side of my integrated amp's "AUX" input jack. Low and behold, I only
get music out of the right side speaker.
If I unplug that IC, and plug the other IC (1 pair) into the left side of my phono stage
(again "high out") then into the left side "AUX" input jack of my integrated amp, You
got it, left side sounds great, nothing out of the right speaker.

Now, when I plug them both in (as in normal connection of phono stage to amp) I get
95% of all music information out of one side, and yes, WTF only 5% out of the other
speaker.

All cables are securely connected. Any suggestions or ideas would be greatly appreciated.

Hi, markj941,

The JD9 uses dip switches for left and right channels for gain; check to be sure that the dip switches are set to the correct position for each channel.

Regards,

Tom

Tubes are my guess, on the integrated amp since all inputs give same results.  Is there a phono stage on your integrated amp you could try?  Gold Lion tubes are affordable.

Although some of the reported observations seem inconsistent with the possibility of a polarity reversal in one channel (which could conceivably result from a miswire in the new turntable, or even a miswire within the cartridge itself), to be certain that isn’t causing the problem I would suggest that you try reversing the + and - connections to one (and only one) speaker, at either the speaker end or the amp end of the cable (but not both).

As you may be aware, a polarity reversal on one channel can have strange effects on image position and focus when both channels are playing, but would not affect sonics significantly when only one channel is playing.

Sounds like the preamp/phono stage as others have stated. 
First level of contingency is backup so,  
I would sub in your backup preamp/phonostage to confirm.
Good luck

I propose you are confusing the setting for your cartridge.  You have a high output MC cartridge which will require the same gain setting as a MM cartridge.  So that means a low gain output setting.  

You refer to to a high output setting which is the exact opposite of what you want with a high output MC.  I looked up the spec for your phono stage and it provides a whopping 85 db on high and even a seriously high 60 db on the low setting.  Most phono stages provide 40 db low and 60 db high.

 I think you are overloading the input on the preamp.  Try the lowest gain setting.
