Two, NEW, Zenith-Sylvania 6L6GA, shouldered glass, wartime, match date pr, 6L6GA
Two, NEW in box, Zenith-Sylvania 6L6GA tubes, with the shouldered glass envelope. These are of course exact equivalents to the 6L6 and 6L6G tubes- but should not be used in applications calling for the 6L6GC. Tested on a Hickok TV-3 military tester that has been calibrated, just to make sure. Firm bases, black plates, excellent silvering (typical 1944 Sylvania silvering, think to look like Mullard). Tubes are matched for dynamic gain and structure- test at 5625, 5500 where pass/fail is 3150 micromho. The tubes have the same structure inside and out, having matching date codes of "Y4R", December 1944. M-R (printed on the bases and the boxes) stands for "Maintenance-Repair", which was a designation exclusive to wartime- meaning this was intended for civilian use. Many other lots of tubes for sale this week.
