811A Tube, RCA, 1958, Made In USA

This is a used tube from the collection of a retired engineer.  He had plenty of new 811/811A tubes, and a few that were used, kept in boxes, and saved.  This is one of the used ones.  From what I saw of his setup, he didn't save bad tubes, so I believe this tube works.  HOWEVER, I cannot say with 100% certainty that it will.  

Visual inspection finds nothing wrong, but that may mean nothing.

This tube has a paper sticker on the glass bottle, which can be removed with a little effort.

Bottom line is, I feel pretty sure this tube will work fine, but since I cannot guarantee that it will, I'm pricing it accordingly.  

This will be double boxed (tube box and shipping box), and padded appropriately.  I'll pack it like it was a $100 tube, to do all I can to make sure you don't get shipping damage.

Since I have no personal experience with this tube, it is being sold as is, no warranty, no return.

Ships safely and quickly from Mississippi.
