Svetlana SED 6L6GC - matched pair, 1999
The 1999 Svetlana 6L6GC tubes in this precisely matched pair have plates with square holes and dual dish getters. They were made at the original SPb factory in St. Petersburg before the Svetlana logo was purchased by New Sensor. The gold print on the glass has the Svetlana logo and reads, "Svetlana Electron Device, Inc. Made in Russia" with matching date codes ("99 21" = 21st week of 1999).
Tubes test as new and are matched for both plate draw (47.6 & 50.0 mA) and transconductance (90% & 95% Gm). They ship in new white boxes with test results for each tube.

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
Price per matched set: $169.00
