Two, Cunningham CX-71A,#71A tubes, with the globe/balloon glass envelope. These are of course exact equivalents to the UX171A/UX-171A, CX371A/CX-371A, 71A, and 171A tubes. Used and tested on a Hickok TV-3 military tester that has been calibrated. Firm bases, excellent silvering. Tubes are matched for dynamic gain and structure- test at 1925, 1875 where pass/fail is 1040 micromho. That is about as strong as it gets on my tester. The tubes have the same structure inside and out.

Many other lots of tubes for sale this week.
