RCA ONE (1) JAN-CRC-6AS7G Double Triode tNOS AT1000 TESTED Vacuum Tubes 6AS7 Audio 1945-1960

This listing is for one (1) JAN-CRC-6AS7G Double Triode 6AS7 vacuum tube in the ST (Coke bottle) tube shape. It has a black bakelite octal base, black plate, and bottom D getter.

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 80 mA and 120 mA AND transconductance must measure between 4640 uMhos and 6960 uMhos, consistent with original 1945 RCA, Western Electric, 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 10 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!
