Two, Tung Sol 5U4G tubes, with the tall, shouldered glass bulb. There are obviously, vintage, US made Tung Sol tubes and not the modern day, Russian made re-issue/reproduction Tung Sol tubes. Black plates, off white logos, with the lower silvering. Tested on a Hickok TV-3 military tester that has been calibrated. Firm bases, excellent silvering. Tubes test at 162-160 and 160-158 where pass/fail is 80. These are relative numbers and do not indicate percentages. Actual new in box, p...ostwar 5U4G tubes test 165+/-5 on my tester, so these are very strong. Tubes have the same structure inside and out, having matching date codes of "322432-3", the 32nd week of 1954. Many other lots of tubes for sale this week.Shipping is free within the continental US. Elsewhere- exact postage only, no packing fee.
