This is one rare tube. Made by RT in France for Mullard. The tube has blue glass in places where plates open up to reduce electron emissions. The tubes is crazy transparent, which is good, but could be bad in some systems. If your system is already bright or your headphones are lean and bright, think HD850 – this tube might be too much. with my HD650, the sound was very detailed, dynamic and sparkly. Sound stage was just huge! All in all a beautiful looking and sounding tube.
