Tube Readings?

Help me understand tube testing. I'm looking at a pair of 6AK5s on ebay, and the seller doesn't specify whether they are matched or not, he just says "TEST RESULTS WHERE: 1850, 1800 AND MINIMUM READING IS 1300."

What does this mean?

Thanks,
Tri

I always assume the tubes are not matched unless the seller specifically states they are. You could also try: Antique Electronic Supply

The figures quoted are transconductance so they are a pretty close match.

Did he say what tube tester was used?

Yeah, he said it was a Hickok 539B.
