Two, new in box, RCA 6L6G tubes. These can of course be used in applications also calling for the 6L6 and 6L6GA tubes. Tested on a Hickok TV-3 military tester that has been calibrated, just to make sure. Firm bases, dual D-getter, excellent silvering. Tubes are matched for dynamic gain and structure- test at 5500, 5312 where pass/fail is 3125 micromho.  The tubes were also matched on a "Maximatcher", at fixed bias, having plate currents of 21.5 ma and 20.7 ma.  The tubes have matching date codes of "426", the 26th week of 1954.  

Many other lots of tubes for sale this week.
