Two, RCA Radiotron UX-245, #45 tubes, with the globe/balloon glass envelope. These are of course exact equivalents to the CX345/CX-345, 145, 245, and 45 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 1800, 1750 where pass/fail is 1170 micromho. The tubes have the same structure inside and out.

Many other lots of tubes for sale this week.
