SOLD!These are wonderful tubes and the earliest version made from 1956 to 1960. They were tested on my B & K Dyna-Jet 707 and you can see the results.
These have an airy, open top end without being bright, superb bass, and a big, holographic stage. Copper support rods.
They come with their Radiotechnique boxes.
