Howdy all,

I just walked out of a thrift store with a box of probably over 100 vacuum tubes all jumbled together.

When I get home I will inventory them and organize them and try to come up with some kind of storage solution for them.

I have already pulled a few that clearly had compromised envelopes and no vacuum, but aside from that, I do not have a good way to test them. 

Does anyone have a tube tester or know of a good way to weed out the bad ones?

Also, if anyone is looking for a particular tube for a project, I will probably publish my inventory list on my site when I get it done.

Thanks!
