Two years ago, we become a non-profit with our main focus on lessons. We are liquating many items including our tube stock. These are the best of the best that we have remaining. All tested and ready to install. We didn’t take pictures of all of them. Because if you are reading this, you know what a tube looks like. We no longer have our “Tube Guru”, so we went by what he wrote on the boxes. (1) 5U4G SOVTEK No info looks good.
