One, new in box, RCA JAN CRC 5R4GY, military issue tube. Black plates, hanging filament supports, with the lower silvering, dual D-getter, brown micanol base. Tested on a Hickok TV-3 military tester that has been calibrated, just to make sure. Firm base, excellent silvering. The tubes tests at 164-164, where pass/fail is 80. These are relative numbers and do not indicate percentages. Tube has the date code of "V2E", March-April 1945, wartime manufacture. If you don't have the budget for a Western Electric 274B tube, these are the closest practical tubes you can come to that. |
