I sort and store my NOS ones in Archive or 10 ream paper boxes. I numbered the boxes and made a database of them. Very time consuming, but makes them fairly easy to find. (Up to 90 some cases of them now ! Still sorting out- literally- a 28 ft semi trailer packed full of them. And yes, I do question my sanity at times, as do others here.
). Had to quit, as I was rapidly burning out sorting.
I have cardboard bin boxes in my garage, with tube numbers on them, into which I sort the good, tested used tubes. I find Steam Punk folks like the bad ones for projects, so they get recycled to them.
Makes it easy to grab the bins, put them in boxes and haul them to the Hamfairs.
