NOS GE Canada 6L6GC Matched Power Tube Set

I bought these overseas but never used them. They are meant to be some of the best you can get. This is from the original seller:

Tubes feature Grey plates with Side getters and clear tops.  Tubes are current matched and ready for your vintage amp! Tubes have been tested on a recently calibrated Hickok TV7 tube tester with a digital meter. Tubes test as follows:

Tube 1 : 38.7

Tube 2 : 37.

Minimum good test value on a TV7 tester for an 6l6 tube is 25. The tubes all test within or near the NOS range.
