With an 845 compatible amplifier, it is easy to use as an ``845 compatible tube'', reducing confusion when choosing a bulb. The finish is also clearly made into a \"molybdenum specification\". ER242\/ER284 uses a new base with a black base + Teflon bottom, and the molybdenum plate specification uses a single silver wire for the wiring inside the base.
