Five, Dynaco-Telefunken 12AX7/ECC83 tubes. Long, smooth, 17 mm grey plates, top halo getter These are branded Dynaco, "Made in Western Germany"- but were manufactured by Telefunken for the amplifier company, Dynaco..The tubes all have the "diamond bottom", in the region between the pins. Tested on a Hickok TV-3 military tester that has been calibrated. Straight pins, excellent, original logos, excellent silvering. Tubes are matched for dynamic gain and structure- test at 193...8-1938, 1938-1938, 1875-1875, 1875-1875, 1875-1875 where pass/fail is 700 micromho. The Hickok TV-3 testers only equivalent is the Hickok TV-10, and there are no other Hickok testers that bias the 12AX7 as these two models- don't compare the result to a Hickok TV-7 or 539. They have the same structure inside and out, having date codes of "GG", "GG", "GG", "GI", and unmarked. They were harvested from the same Dynaco setup.Many other lots of tubes for sale this week.Shipping is free within the continental US. Elsewhere- exact postage only, no packing feee
