FS: a pair used RCA 12AU7 tubes. Both are identical USA 1950's tubes, large charcoal gray (black) plates, D getter, white printing - some of the printing is rubbed - see pics.Tubes tested strong on my calibrated Hickok 539C tester.
Both 2800 - 3100 on each triode (minimum 1900). Triodes measured 8.5 mA to 10 mA current. These are good tubes I was saving for my own projects, but letting them go to someone who can use them. They are often considered the best of the 12AU7 variety. Will be well-packed, individually wrapped, in box and shipped within the US free of charge by US Postal. Buyer will receive 2 tubes.
Thanks for looking,
Peter
