RCA Cunningham Radiotron Number Type 80 Vacuum Tube Rectifier Black Plates Engraved Base Shoulder ST Shape Hanging Filaments Harcourt Brace I am playing them asThis RCA Cunningham Radiotron number type 80 rectifier tube was tested on our Paul Hart calibrated TV7 U. It measured 47 44 where minimum (65%) is 40 40 and 100% is 62 62. It teats below spec but should work fine in many applications. It has a dimpled sheet getter; an engraved base; hanging filaments and outstanding flashing. WE HAVE SCORES OF THOUSANDS OF VACUUM TUBES. IF IT'S NOT LISTED, WE MAY HAVE IT.
