A factory QUAD Platinum Matched Tung-Sol 5881 tubes.  These are burned in for 24 hours and then factory matched at real world voltages for current and transconductance.  The test results are labelled on each tube box as shown.  These are difficult to find at a reasonable price, so this is an opportunity to obtain a world class tube at a price that won’t break the bank.

These are made in the Xpo-Pul factory (also known as Reflektor) in Saratov, Russia.  They are all recent date codes.

All tubes carry the 90 day factory warranty against defects from date of purchase.
