Two, Tung Sol 5U4G tubes, with the tall, shouldered glass bulb. Black, plates, with the lower getter and silvering. These are obviously, vintage, US made, Tung Sol tubes, and not the modern day, Russian made reproduction/re-issue Tung Sol branded tubes. Tested on a Hickok TV-3 military tester that has been calibrated. Firm bases, excellent silvering. Tubes test at 156-155 and 155-152 where pass/fail is 80. These are relative numbers and do not indicate percentages. New in bo...x Tung Sol 5U4G tubes test 160+/-5 on my tester, so these are very strong. Tubes have the same exact structure inside and out, having date codes of "322451-3" and "322429-3", the 51st and 29th 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.
