Description

This military spec 1970s GE 5998A is an uprated 6AS7G/6080 dual triode tube type. It has black plates and a halo getter. The white print on the base has the GE logo and reads "JAN-5998A."

The 5998 can be used in most audio circuits designed for 6AS7G/6080 tube, but the 5998 draws slightly less current and has twice the transconductance.

Testing

This tube tests as new with very low noise. It was tested at typical operating voltages on a laboratory grade Amplitrex AT1000. This testing process also includes screening for gas, heater-cathode leakage, and shorts. This tube has also been screened for noise and excessive microphonics in our OTL headphone amp.
