Description

This early 1960s GE 12AX7 tube has long gray plates and a horseshoe getter. The red or white print on the glass has the GE logo (partial).

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. 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.

Pricing

This tube is sold individually. Photo is a sample from the lot. It ships in a new white box with test results for current draw (mA) and transconductance (Gm).
