I put together a new turntable set-up consisting of a Garrard 301, a new SME 2012 M2 tonearm and what I was under the impression was a new older Shure V15 Type 4 cartridge.Looked new at least!
My dilemma is that I have no left channel audio coming out of the TT.
The bias was a bit off so I corrected that, the cables appear all connected property to the amp from the tonearm, wires from the cartridge/headshell are correct, so what else should I be looking at?
Any help would be much appreciated.

Swap the left and right cartridge wires. If the problem moves to the other channel, the cartridge is faulty.
I am sure that you checked the continuity of the interconnects and tonearm wiring, so I won't suggest that. :wink:

Your multimeter is your friend. Confirm you have checked all the wiring with it, not just a visual inspection. Swap L/R at the amp phone input is a little easier than the headshell wiring, or at the headshell as QZ suggests..

Once you find the problem and correct it, do share a picture of the new baby!

The reason that I suggested the cartridge wires first is because I suspect the cartridge is faulty, and it will rule out tonearm and interconnect wiring as the culprit.

Ok swapped the Red right channel on the cartridge with the left channel white line and the
audio did move to the left channel that had previously been very low and the right now low or near dead. Would appear to be the cartridge!
I then put a different headshell on the SME Tonearm with a MM , switched the amp to MM and the same issue presented !!
Yikes
