    Description

    Two, new in box, Sylvania 6SN7GTB tubes. Opposing,  angled T-plates, chrome top getter, "coin base"-no bakelite base. The 6SN7GTB can of course be used in applications calling for the 6SN7GT and 6SN7GTA. Tested on a Hickok TV-3 military tester that has been calibrated, just to make sure. Firm bases, excellent silvering. Tubes are matched for dynamic gain and structure- test at 3375-3250, 3250-3250, where pass/fail is 1625 micromho.  The tubes have the same structure inside and out, having matching date codes of "ba APK", late 1970's.
