Description |
According to the nomenclature for American Octal tubes this tube would be a metal tube, as no suffix -G or -GT is added to the designation 5Y3, indicating the glass versions.
However this tube never appeared as a metal tube, but only in the glass versions 5Y3G and 5Y3GT.
Some manufacturers also stamped glass versions as 5Y3 only, contrary to the agreement, as the picture shows.
Also in schematic diagrams these suffixes are often omitted.
