Testing

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

This tube is sold individually. It ships in its original box with test results for current draw (mA) and transconductance (Gm) for each triode section. Photo is of the actual tube.
