For more information, see data sheet :http://tubezone.net/pdf/3d21wb.pdfand http://tubezone.net/pdf/3d21a-curves.pdf and http://tubezone.net/pdf/3d21a.pdf
These are individually tested on an AVO precision tube tester. I am guaranteeing for these 30 days against defects (but not breakage, so don't smash them with a hammer!), so long as you're willing to mail back anything that doesn't work right.
