Cartridge without serial?


Hey everyone,

Curious as to if anyone has ever purchased a cartridge without a serial number? I'm looking to purchase a cartridge, but the seller has mentioned it doesn't have a serial number, which thus no warranty. Mind filling in my feeble thoughts as to this being a scam? Seller has zero bad reviews and hundreds of positive ones, but isn't based in the US. Any help is appreciated!

@daveyf I'm tired arguing with you, if you think a manufacturer like ZYX and its designer Nakatsuka-San with at least 50 years experience in cartridge manufacturing can't make a thousands of cartridges nowadays under his own brand then high-end market must be completely dead. But again, they sell them all over the world, USA is a huge country, they sell in Russia, China and whole Europe ... Also they make so many different models from expensive to very expensive.  
@chakster  LOL, If you think that ZYX or any high end manufacturer of cartridges, with the possible exception of Ortofon, is making and selling ’thousands’ of cartridges annually, i have a nice bridge I can sell you....
I found a pic of the serial number on the back of my cartridge.
It reads C3724 and it doesn`t match the serial number on the booklet.
Interesting...
Just checking ebay for Zyx and what caught my eye is that ones coming from Asia (known seller), and selling as new, are not perfectly packaged, missing the outer cellophane bag with a parallel sticker where cartridge model is printed, type is written by hand (manufacturer?) and serial number stamped. Box should have the serial number as the destination country initials. Both Zyx cartridges i have bought from local distributor here in Athens had serial number on cellophane bag, box and typed on manual, and the country initials (GR). Just check ebay to have a better picture. My simple understanding is that refurbished models are travelling around.


@petg60 yeah, thanks for posting this.

if it sounds like it’s broken then your Zyx it’s a fake made in china extracted from an Audio Technica AT 95!!!    LOL
