Sylvania etc. ONE (1) 6V6GT Beam Power tNOS AT1000 TESTED Vacuum Tubes greyglass 6V6 Audio 1943-1958

This listing is for one (1) 6V6GT Beam Power 6V6 vacuum tube in the straight-walled glass tube shape. It has a black bakelite octal base, grey or black glass from a coating used as an RF shield in early tubes, black plate, and bottom or top getter. Labels in stock include Sylvania, CBS, Raytheon, Tung-Sol, Ken-Rad. If you're looking for a particular brand, please message right as you order - we pack and ship quickly!

Your tube has been fully tested on a computer-regulated, USA-made Amplitrex AT1000 on Fixed Bias setting with like new, NOS results (tNOS). Here's what that means: to qualify for this listing, several stringent conditions must be met: The plate current must measure between 36 mA and 54 mA AND transconductance must measure between 3280 uMhos and 4920 uMhos, consistent with original 1943 RCA, Sylvania, GE, and/or Tung-Sol datasheet specifications for new tubes of this type. The tube must also show no shorts, show a gas current less than 4.5 mA, and a heater-to-cathode leakage of less than 10 microamps (10 uA). The tube might have mechanical wear or have the label rubbed off - these are very old! Used-testing tubes are available in a separate listing at a significant discount. Every tube you receive from Sound By Doc is guaranteed against failure for 60 days after purchase, an industry extreme!
