Description

This 1966 Siemens tube is said to be one of the finest 12AT7 / ECC81 tubes ever made. It has gray plates, triple micas, and a halo getter with dual support posts. The white label has the Siemens logo in excellent condition and the code for the Munich, Germany factory is etched in the glass. 

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.

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. Photo is of a sample from the lot. Matched pairs, when available, are listed as Item 749.
