6SN7WGTA / 6SNGT Sylvania/USA, black base
NOS 6SN7WGTA black base, Sylvania/USA JAN
Datiert: 1974-1979
This type indicates a military spec tube that was not made for consumer use. These usually have extra support posts on the plate structure, heavy mica spacers, and black bases. These also have the famous triangular shaped black plates. They have been ruggedized to withstand shock. The early Sylvania 6SN7W types from the 1940s had a metal collar around the base, then later a black base. These look internally alot like the early Sylvania GTA types listed above. Sylvania made these for other brands as well, including RCA. Easy to spot as they have the triangular blackplates facing each other in a short bottle, with a very heavy chrome top flashing extending down the sides of the tube. These are RARE and worth seeking out! Only the WGTA types made in the mid 70s to the 80s reverted back to black bases then coin or wafer bases. These are all wonderful tubes, are long lived, and sound fantastic. No wonder they are fast disappearing from the vintage tube market.
