Testing

This tube tests as new with high gain. 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. See product options for current availability.
 
Noise and microphonics

This tube tests as "phono/V1 grade"--the quietest range for noise and microphonics--on our custom noise testing equipment. It is an excellent choice for sensitive applications such as microphone preamps, V1 positions, DA converters, and phono stages.
