Precision Power Tube Matching

Our power tubes are burned in for 48 hours 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.

The questions listed below allow you to provide information about your operating conditions that will help us select the best matched set of power tubes for your amplifier. Why this matters
1. What is the manufacturer and model of your amplifier?
2. How is your amp biased?   Why we ask
