I think we're in good shape, the seller just messaged me and said he put a pic of the Toshiba boxes up on the listing. I think he is a professor at Ohio State University, for what that's worth. I might have to buy more of the 74s unless you guys beat me to it. Almost everyone is out of them.
I bought these some time ago, maybe a year or so
4 matched quads for B1
and two matched quads for F5
sure hope I don't burn them
writing looks 'yellowish'
but like said, minor details that may have changed over the years
but no doubt, mine look very clean and shiny
why didn't I buy 50 unmatched 74 instead of 170
whatever, in a couple of years we may be building something different, who knows

The price keeps going up. It is now 350 USD for 200, getting close to "normal" price.
Just a word from my experience. About 4 years back, I bought a Sony power JFET from a very reliable dealer, as a collector's item. The device is genuine, and still functions largely as per catalog, but the grade (like Idss if you like) is quite far off the specification. So even though people say transistors have unlimited shelf life, some long-term changes do take place.
Not a total surprise, considering how transistors are made (doped silicon).
