Sylvania 12AU7 12AU7A ECC82 Vacuum Tube Valve CONN-Selected For Your Bottlehead

This Sylvania-MANUFACTURED, CONN-BRANDED and CONN-SELECTED 12AU7A / ECC82 dual triode was tested on our Paul Hart-calibrated TV7/U for shorts, gas and transconductance. There were no shorts or gas. Transconductance measured a perfectly-balanced 72/72 where minimum (65%) is 56/56 and 100% is 86/86. This tube has narrow, gray, 16 MM plates; good flashing; a top, O getter; copper support rods; excellent silkscreening and 312 639 provenance/date codes. These tubes were selected by CONN Organ for musicality and clarity. I played it in my Bottlehead Crack and it sounds outstanding -- dead quiet when the CD player is paused with excellent frequency response, sound-staging, and dynamics. WE HAVE SCORES OF THOUSANDS OF VACUUM TUBES. IF IT'S NOT LISTED, WE MAY HAVE IT.
