These unusual 1960s Mullard 6SN7GTB tubes have medium bottles with black plates and bottom getters, similar to RCA 6SN7GTB tubes. The white labels on the glass have the IEC International C logo (partial).
Both tubes test as new with very low noise. They are matched for both current draw (mA) and transconductance (Gm). They have been screened for gas, heater-cathode leakage, shorts, and excessive noise and microphonics on each triode section. They were tested at typical operating voltages on a laboratory grade Amplitrex AT1000 (manual setting, fixed bias mode). Learn more about our testing process here

Tubes ship in their original boxes with test results for each triode section.
