Guess the Tube

Here's a tube from my stash that I picked up
in a cluster of transmitter-tubes,
which I bought for the large round bulbs.
If anyone knows what it is, they can post a comment!

Welcome Tube Admirers.

Yet another blog about tubes and tube circuits, gear etc.
Hope you get some enjoyment out of it

 How a tube looks to God, when He chooses to look at one this way.
