Marconi 6L6GC - matched pair

Marconi 6L6GC - matched pair
Manufacturer: Marconi
The Marconi 6L6GC power tubes in this precisely matched pair have gray plates, dual side getters, and black bases. The white print on the base of one tube has the GE logo and the red print on the base of the other tube has the Marconi label. "Made in Canada" is faintly etched in the glass. This pair is discounted because one tube has a repaired guide pin (does not effect tube performance).
 
Tubes test as new and are matched for both current draw (52.0 mA & 52.2 mA) and transconductance (93% & 95% Gm). They ship in new white boxes with test results for each tube.

These tubes are sold as a matched set. Photo is of the actual tubes.

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
