NOS Western Electric Engraved Base 300B, Black Plate, Late 1930's, Matched Pair
We have unearthed a pair of the most desirable, hard to find and best sounding 300B available on the planet. These are the fabled Engraved Base, Western Electric 300B from the late 1930's. These tubes are unused (New Old Stock) and absolutely perfect. Tested on a calibrated Western Electric KS-1587 4-L2 tube tester, they test 115% of new and are matched to within 1%. The getters are large and beautiful measuring 3 1/3 inches wide x 2 1/2 inches tall. The getter rings are the large “O” washer style. The bases are tight with no loose particles inside the glass envelope. Even the base pins are oxidation free and very shiny. The original boxes have the old style "seal" and are in perfect condition. Inside the boxes, the tubes are wrapped in their original cellulose which is wrapped inside the original corrugated cardboard. This is how they came from the factory eighty years ago. Yes, we know the price is very high, but we paid *a lot* to get these. If you want the best pair of 300B available anywhere, this is it.
