This 1958 Siemens
12AT7 / ECC81 tube has a halo getter and gray plates with copper grid posts. The white label on the glass is missing and the code for the Munich, Germany factory is etched in the glass. 

This tube tests as new with very low noise. 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.


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. Photo is of the actual tube. Matched pairs, when available, are listed as Item 749.
