I have kept my stash of tubes/valves in a few odd cardboard boxes. Each time I go digging, in have to rummage a bit to find what I’m looking for. I asked my wife for a recommendation and she suggested craft boxes. So, off we went to Hobby Lobby. I came home with two ridiculously perfect solutions—one for power tubes, another for preamp tubes. Now I can see exactly where every tube is and keep the stash stocked. (I may need to purchase another box for my vintage NOS tubes…) Hope this provides some inspiration on a cold December day.
