These are burned-in for 24 hours and then factory matched at real world voltages. Finally the test results are labelled on each tube box.
The Tung-Sol 6L6GC STR tubes have excellent linearity, power handling capacity and heat dissipation and built to withstand the heavy rigors of higher plate voltages.
They are all recent date codes.
The factory matches these tubes at 400V Plate, 250V Screen and -20.52 V bias. Insist on factory platinum matched tubes for best performance.
All tubes carry the 90 day factory warranty against defects from date of purchase.
I have been selling tubes of all types for more than ten years. Buy with confidence.
