Mint STRONG matched PAIR identical GE 7581A KT66 "OO" getter tubes from 1960's (one labeled for CEI) in original boxes.Nicely matched within about 3% Gm (mutual conductance) and about 3.1% mA (current) between them. Auditioned in my amp to insure they perform well together and they sound wonderful with nice crisp highs, excellent clean detail and soft solid bass! You can safely use these in amps that call for 7581, KT66 or 6L6GC tubes without any mods.We may have others, click here to see ==>> Debi's Vintage Electronics BoutiqueTube Number 7581A KT66 (aka 6L6GC) Brand on tube CEI (worn)Actual mfr GECountry of mfr USADate codes --,--Box type original (one CEI, one GE)Plate style GrayGetter style Double "OO" sideGlass style Clear bottlesTest results (typical NOS = 5000 Gm @ 45mA5250 Gm @ 50.0 mA5100 Gm @ 48.5 mA
