No right channel in new cartridge


I just got a Sumiko Blackbird & mounted it.  I have no right channel. I haven’t fine tuned the mounting but, That shouldn’t make me lose a whole channel.  Once or twice I’ve heard a hum in the right channel before I put the needle down. When it goes down it stops & goes silent.  The channel isn’t effected in CD, DVD or radio.

i bought it here(all positives on the seller) & it only had 10 hours on it. It didn’t come in the original box but came screwed into a box... seemed pretty secure.  I checked & reconnected all the pins, jacks into the AVR & ground wire.

What should I try next?

I do not remember if you said how you paid but at this stage they are obviously not going to refund you willingly so....
If via PayPal just initiate a claim as soon as you verify they have received it.
If by credit card go through them, again once you know they have it back.

You could may well have aggravated the situation by commenting on it here but sounds like it is past civility now.
Best of luck with this and don't worry about their blow hard talk of Police involvement. Across state lines. Really?

Call the police? For what criminal or civil charges? This guy's aggro. Let PayPal handle things. They almost always side with buyer. 
I don't know why you're even thinking about it.   Just return it and be done.  If the seller guarantees a repaired Soundsmith cartridge, let him return it, then send it to you

I’m asking for options on another thread too.  I know this thread Is a bit old.  If anyone’s reading, I’d like to ask for opinions.  Scott at Aris Audio was rec’d on several threads.  He’s offered a new Ortofon Quintet Black S for $855 new. He believes I’ll enjoy it better than a DV 20x2 or Karat 17D3 (on sale he’s selling the 20x2). I enjoy just a tad.  Thoughts?
