Help!

Hello, yes, based on your advise and others I tried everything, I think they know where the issue is, at least I hope they do! Will post here when I find out the problem. Thank you again 

gnaudio, Did you do the swapping necessary to prove the problem is in the EAR? I guess you did.

Thank you everyone for your assistance. I spoke to the EAR USA tech who told me that the meters run through the volume control circuit so it’s on its way back to England for repairs. EAR is the best customer service company I’ve met in the audio hobby. I’ve had a couple issues but they always stand behind their work. Will update when I know what the problem was.

 When you say you swapped cables at the pre-amplifier, do you mean to say you swapped cables at the output of the pre-amplifier to the amplifier or at the input to the phono stage? Because if you did the latter that is no different from swapping the cartridge pins except you have tested the cables themselves. My suspicion is that one channel is out on your pre-amplifier. The reason you have signal in mono is because you are hearing the right channel only but now it’s shared with the left. So, if you didn’t do it already, swap the cables that go from the preamplifier to the amplifier. Let us know what happens.

Ok, thank you. So I swapped the RCA cables at the preamp and the right side continued to play music, nothing from the left channel. I then swapped the left and right cartridge clips around and the same thing, only sound from the right channel. I even tried another pair of phono cables with the same result. I even tried the second phono input on my preamp, same right channel only playing. A little confused now. Any advise?

Swap your LP RCA channels. This will confirm its the Left that's the problem. Next swap channels on the cartridge pins. Then either its the cartridge, or somewhere between the cartridge clips and the RCA ends. So which is it?
