Testing
This tube tests as new with balanced sections. 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.
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 a new white box with test
results for current draw (mA) and transconductance (Gm) for each triode
section.
