No right channel in new cartridge

If your Sumiko Blackbird is a High Output version (2.5mv) you can check it with volt meter to make sure.

If your Blackbird is a Low Output (0.7mv) version then you can send it for inspection to professionals.

You need another cartridge to check your phono system, mormally this problem is a lack of connection when you mount a new artridge. You can also check your tonearm wires with a tester (left and right) to make sure you didn't damaged one of the pin.

If you think your cartridge is broken then definitely return it for full refund, do not send it for refurbishing even if the seller cover the cost. Simply buy another cartridge, you can buy a much better cartridge, let me know if you need help.

In my experience with used cartridges only 1 out of 50 has a broken coil wire and it was the cheapest cartridge.

"Never buy a used cartridge" - this is the worst advice from people who knows nothing. More important is who is the seller!

If i were you, i would return the cartridge for full refund to buy perfectly working cartridge from another seller. Cartridge coil wire does not break in transit normally. Some sellers on here just re-sell stuff they never even tried, i’ve been cheated a few times by audiogon sellers with big score. Hope your seller is not from California?

It’s more safe when you buy a personal cartridge from a collection, tested and guaranteed to work as described.

Not sure why do you need an MC cartridge, they are the most problematic as you can see.

Tochsi, yes, swap red with white, then blue with green, then hook it up and listen, and don’t let anyone make you anxious. Sounds like you are dealing with a responsible seller and it’s still possible that the fault lies in your system. (I have purchased many used cartridges in my life with no issues.) 

Thanks everyone.

The dropped channel followed the change in leads.

I have loaner from a friend.  It’s Sumiko Pearl he got this yr, never did a second setup for the teens.  So, he never used it. And, both channels work.

Several people said just return it & get something else here. I looked for a while here (consensus this is a very trusted site-but still check the seller) & on other sites. I found this for $550 barely used & the seller has an excellent rep.  It’s a chance to safely jump 1 or 2 levels.  I tend to trust people & he just seems like someone it’s worth working with.  Since I have a loaner, I’m lucky enough to be able to wait 6 wks to get it back. If the SS repair assessment says it’s something bigger, I’ll return it. 

You’ll all laugh but, I had sooo many recd brands & models that I setup a small spreadsheet: Brand, Model, Price, New Price, Sound Characteristics, Review Consensus, Misc. And, I don’t “relish the idea” of going back to it. lol

There are better cartridges even for $500, i paid same price for my Dynavector KARAT 23RS MR Ruby in NOS condition for example. There are many options for MC or decent MM for the same price.

SoundSmith will have to open your cartridge, sometimes it means to break the cartridge and glue it back (not sure about Sumiko). Not sure why do you need all these damage if you’re not even sure he can fix it? Fixing coil is not cheap at all. Reparing coil wire is actually very expensive. Are you sure he can do that in 6 weeks? I think your cartridge will be inspected in 6 weeks. But It can take 3-5 month to fix the problem.
