Default 6C33C tube stamp

Hello...

I purchased some 6C33C tubes on Ebay and found that some of them were labeled with the stamp below.

Click the image to open in full size.

I decoded the text as "rechecked" or "retested" but my question is about the "X". Is this a tube that failed quality control?
