- WE300 specification! ATM-300 is the most popular among air tights. It is equipped with a Tamura output transformer and has a luxurious construction using a copper plate on the bottom. The clear sound of the violin and the power to make a large speaker sound in a dignified manner are impressive. The gain will also increase enough, so I think it's okay to bring out the full appeal of 300B by connecting directly to the CD.

- Beautiful item! An air tight tubular mono amplifier that drives 211 triode tubes that are not often seen in amplifiers in recent years with a single drive. The sound image is large, the middle and high frequencies are easily removed, and the expressive power of the low frequencies makes a bottoming sound. I feel the spirit of Air Tight when they use 211 as the output tube. There are a few small scratches on the exterior, but it is generally beautiful.
