Testing

These tubes test as new with balanced sections.
They are precisely matched for both current draw (mA) and transconductance (Gm). They have been screened for gas, heater-cathode leakage, shorts, and excessive noise and microphonics on each triode section. They were 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

These tubes test as "preamp grade" on our custom noise testing equipment. They are an excellent choice for sensitive applications such as preamplifiers.

 
Pricing

These tubes are sold as a matched pair. They ship in new white boxes with test results for each triode section. Photo is a sample pair form the lot. Singles, when available, are listed as Item 903.
