Description

This 1965 Tung-Sol 12AX7A tube has wide gray plates and a halo getter. The white print on the glass has the Tung-Sol logo.

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.
 
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.
