3 US-Made 12AV5 Vacuum Tubes Valves Lot Of Three North Carolina Press They measured 82/76 for TubeThese three US made 12AV5 output tubes were tested on our Paul Hart calibrated TV7 U for shorts, gas and transconductance. There were no shorts or gas. They measured 64, 67 and 72 where minimum (65%) is 49. One the plus side, these tubes are quite pretty with old fashioned shoulder bottles and should work fine in most applications. WE HAVE SCORES OF THOUSANDS OF VACUUM TUBES. IF IT'S NOT LISTED, WE MAY HAVE IT. PLEASE ALSO SEE OUT ETSY SISTER SITE
