This tube comes from the estate of an audiophile technician who meticulously curated a collection of over 1000 tested and excellent tubes! I will be listing the tubes individually and testing for good or better on a Hickok 799 or Sencore MU140. All writing and measurements on boxes were made by the previous owner and although I believe them to be accurate, some variation may occur. See the last photo for an idea of the span of the collection. This photo is for context only. This listing is only for the tube represented in the title. Feel free to ask questions! I have been a recording engineer for 20+ years and will do my best to answer your inquiries 🙂
