    This tube is from my personal collection. I had it cryogenically treated to relieve the internal stresses that occurred during the manufacturing process. The result is a lower dynamic noise floor and higher gain. The sound is stunning in comparison to similar untreated tubes.

    This tube is very rare and hard to find in such excellent condition. The pins are clean. There are no loose flakes in the base.

    It has a warm tube sound with extended air and treble, great staging, deep bass extension, very nice texture and decay as well. Absolutely zero grain.

    Shipping cost to be determined based on buyer location.

    If I had funds right now I would buy this tube. I'm gonna keep an eye on it for sure. Hopefully I get lucky!
