It's a perenial question. Once you acquire a big enough pile,
how do you have the slightest idea of what you actually have
and how do you go about finding something when you need it?

This is part one of the solution. a 36" wide 12" shelf with
13 shelves full of cardboard bin boxes. I'm going to have to
order two more shelf units to hold everything here.

As usual, first they get sorted by shape and size. 4-pin
balloon, 4-pin ST, loctal, metal, octal, rectifiers and
so forth. Then as the boxes fill up, "Oh, look, I have 25
or so 6SK7 tubes, they get their own box now."

I spent a coupe of days web surfing and the best price I
managed to find was from ULine. $145 for the shelving
unit, and roughly $50-70 per 100 for the bin boxes.

Unfortunately, I was in a bit of a hurry to assemble things
this morning and made the mistake of using a cheap Chinese
screw driver instead of a decent rubber cushioned Klein. I
know have several holes in my hand as a result. (blisters)

But it's kind of fun to know where all the tubes are. I was
rather amazed to find a good Arcturus 45 in the pile, thee
good 2A3s and a couple of ST 47s.
