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

Tubes that test as “preamp grade” are an excellent choice for sensitive applications such as preamplifiers.
