Two, Tung Sol 5U4G tubes, with the tall, shouldered glass bulb. These are of course, vintage US made Tung Sol tubes, not the modern day Russian made reproduction/re-issue Tung Sol tubes. Black, plates, with the D-getter and lower silvering. Tested on a Hickok TV-3 military tester that has been calibrated. Firm bases, excellent silvering. Tubes test at 168-166 and 165-163 where pass/fail is 80. These are relative numbers and do not indicate percentages. These tubes test where new i...n box 5U4G tubes test on my tester (165+/-5). Tubes have the same exact structure inside and out, having date codes of "322522-3" and "322547-3", the 22nd and 47th week of 1955. Many other lots of tubes for sale this week.Shipping is free within the continental US. Elsewhere- exact postage only, no packing fee.
