Hi i want this pair of tubes but i don't now if they are testing very good, good, ok or better i forget them, can you help me, thanks Gonzalo

TUNGSRAM

MATCHED PAIR

Ia S
mA mA/V
EL84 40.0 11.0
EL84 40.0 11.2
This parameters are measured at Ua = 250V & Ug1 = -7.5V Ug2 = 250V

Without knowing what the "nominal good" or "minimum acceptable" numbers are for the EL84, those numbers are completely useless, except to say the tubes are well matched. If they are good or not, those numbers do not say, without being able to reference what the test results "should" be.

The only way to know is to use a tube tester. Those number doesn't prove anything.

Thanks a lot for the answers, normally ebay sellers says tested strong or ok but this one only gives this data so i was thinking that was the test.
Ok i'll ask to the seller, thanks again.

I like those Tungsram EL84's, so you got a good deal. Tuberolling is the quickest way to kill one's pockets for sure..
