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 sensitive applications such as microphone preamps, DA
converters, and phono stages.
Pricing
This
tube is sold individually. It ships in a new white box with test
results for current draw (mA) and transconductance (Gm).
