This tube tests as new with balanced sections and very low noise. It has been screened for gas, heater-cathode leakage, shorts, and excessive noise and microphonics on each triode section. It was tested at typical operating voltages on a laboratory grade Amplitrex AT1000 (manual setting, fixed bias mode). Learn more about our testing process here.


This tube is sold individually. It ships in a new white box with test results for current draw (mA) and transconductance (Gm) for each triode section.
