    90+year old tube and spec sheet.

    Thought you guys might find this interesting. I picked up 4 used UX201A tubes, in the boxes. One of the boxes had a good spec sheet in it. The others just fell apart when I took them out.

    They aren't that uncommon - I see them on EBay for about $12 apiece. What might be valuable to a collector would be the box and spec sheet. Unfortunately, this was a really common tube for a long time, so there are still lots of them out there. It started out as the DeForest 201 before RCA bought out DeForest.

    No. Getting old is nothing like a transistor.

    I have paid $20 a pop for a good used one from a dealer.
