Original Description:
Two, Tung Sol #45 tubes, with the shouldered glass envelope  These are obviously, vintage, US made Tung Sol tubes and not the modern day, Russian made reproduction/re-issue of Tung Sol tubes. These are of course exact equivalents to the UX245/UX-245, CX345/CX-345, 145, and 245 tubes. Used and tested on a Hickok TV-3 military tester that has been calibrated. Black plates, firm bases, excellent silvering. Tubes are matched for dynamic gain and structure- test at 1950, 1850... where pass/fail is 1170 micromho. The tubes have the same structure inside and out, having date codes of  "19" and "17", two months apart in 1943.
Many other lots of tubes for sale this week.Shipping is free within the continental US. Elsewhere- exact postage only, no packing fee.
