Suggestions Please-Sound coming out of one speaker

Hi Friends.
I recently moved my setup from one room to another and when I setup my turntable, sound is only playing out of one channel/speaker. I'm going to try to describe the situation and hopefully I can get a potential diagnosis of where issue could be in my system.

I connected a new Denon 103r cartridge to the four tone arm wires correct. I can't see any issues with the wire connectors on the tone arm wire and the pins on the cartridge. I have the cartridge hooked up to a OL Silver arm. This arm has the IC's connected to the tone arm wire. I connected the IC's to my Supratek Pre-amp, which has a built in phono stage. The pre-amp is a tube driven. To try and locate the issue, I switched the right and the left IC from the TT and attached it to the pre-amp switched, the sound still came from the same speaker but I would have expected the sound to switch to the other speaker. Just for giggles, I switched the configuration of the wires in my tone arm around and I got some sound from the silent speaker.

I haven't swapped the tubes in the right and left channel on the pre-amp yet. Maybe the issue could be with the tubes in the phono stage of the pre-amp. I'm going to try swapping these tubes out tonight. I hope I don't have any major repair issues, but if I do I want to make sure I can diagnose this issue.

I don't have any issue with sound coming out of one speaker from my CD player.

Any suggestions on what the issue could be?

Thanks.

Jea48 & Elizabeth,
Thanks for your reply. I was leaning toward the phono pre-amp and it feels like that is the culpritt. I swapped the tubes, but felt as if this was a long shot.

Marakanetz, thanks for your help too.

Lewm,
I agree it's not easy to understand entirely what's happening here. I agree with your take on the tubes not being the issue. Regarding what I wrote: "I switched the configuration of the wires in my tone arm around and I got some sound from the silent speaker." There are 4 wires on the tonearm wire and 4 pins on the cartidge to attach the 4 wires. I know the "correct" pattern to hook these up together. When I hook these up using the correct pattern, sound comes out of one speaker, but some sound does come out of the other speaker, I would say 90% of the volume comes out one speaker and 10% volume comes out of the other speaker. When I un-hook these and re-conect using an un-correct pattern, sound still primarily plays out of the same speaker, BUT some sound will come out to the other speaker. I would say the distribution of sound using the incorrect pattern would be about 85% from one speaker, 15% for the other speaker. Using the incorrect pattern probably does not help further identify the issues, but I think it's worth noting.

One other observation I noticed, any sound that was primarily coming out of the speaker that was playing very soft was primarily of the mid-range and low frequencies, I didn't hear any high frequencies coming from the tweeter.
More to discover
