Description

Testing

Both tubes test as new and are matched for both current draw (mA) and transconductance (Gm). Our power tubes are burned in and tested on a laboratory grade Amplitrex AT1000 tube tester (fixed bias mode, manual setting). They are screened for shorts, gas, leakage, and noise. We test and match tubes for both current draw (mA) and transconductance (Gm) at typical operating conditions for no extra charge.

Tubes ship in new white boxes with test results
. These tubes are sold as a matched pair.
