Nice get! He's blocked me, after I posted negative feedback. That was my mistake. I was naive, thinking these Ukrainian, Russian, Moldovan, etc dealers would be honest and not send dead tubes. But I now know you can still get good tubes from them, you just have to test them and consider the 30-40% fails as a cost of doing business.
The '75 you have there is a very good tube, a little different then the plate post version. You can see the curved metal wire holding the getter.
I hope they test well for you.
