I am down to about 10,000. At peak, I had roughly 40,000.

And I am small potatoes...

Some tubes did disappear. I pity the man that wants to get a power
supply for an IBM 709 up and running. C16Js, in used UNTESTED
condition, go for a few hundred bucks. If you can find them.

Same with anyone that gets a computer using 6386 dual triodes.
