Steve:

    That is the dream scenario. All kinds of unadvertised goodies. Cathedrals, breadboards. Boxes of NOS '01s, 45s, 50s and 99s. It never happens to me but I've heard that it happens to others. LOL.

    By the way, that NRI 70 looks awfully similar to a tester I use. I love mine. Easy to operate. With mine, the roll charts contain the newer tubes and a supplemental book contains the old ones. Thankfully, I have both. However, if I didn't have the supplemental book, I would be screwed.

Unless you have both the roll chart and the book, you will be limited in the range of tubes you can test. With some testers, it's the opposite: the roll chart covers the older tubes and supplemental books cover the more modern ones. Again, you need both to enjoy the full range of the tester.
