Description

Two, Arcturus #81 tubes, with the shouldered glass bulb. The #81 tube is of course the exact equivalent of the UX281/UX-281, CX381/CX-381, and 181 tubes. BLUE glass, black plate, engraved logo base. Tested on a Hickok TV-3 military tester that has been calibrated. Firm bases, full gettering. The tubes are matched for structure inside and out, testing at 165, 161 where pass/fail is 80. These are relative numbers and do not indicate percentages. This is a very strong result as the tubes test near new. Many other lots of tubes for sale this week. Shipping is free within the continental US. Elsewhere- exact postage only, no packing fee.
