The Genalex KT66 power tubes in this precisely matched pair have gray glass, bottom getters, and brown bases. They both have Genalex badges (partial—see photos) and the date codes are "NL 4" and "MK 0." One tube has a repaired guide pin (does not affect tube performance).

These tubes test as new. They are matched for both current draw (58.2 mA & 59.2 mA) and transconductance (111% & 111% Gm). They ship in new white boxes with test results.

It is very hard to find matched pairs of vintage power tubes like these—grab them while supplies last!
 
These tubes are sold as a matched pair (2 tubes). Photos are of the actual tubes.
