This tube has been tested to be perfectly balanced in transconductance (Gm) between the two sections. It is appropriate for phase-inverter positions and other demanding roles.

The second 6CG7 variant from RCA is called type T2. It is a grey plate with divider and top getter. Made from '59 to '62.

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 transconductance for each section must measure between 2080 uMhos and 3120 uMhos, consistent with original 1959 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 0.9 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 tNOS or Used Good tube you receive from Sound By Doc is guaranteed against failure for 60 days after purchase, an industry extreme!
