Raising the world of 845 by choosing molybdenum plates
Even if you push the scale of the 845, it will not fail and will continue to resonate with its core.
ELROG ER284 is a model developed as a molybdenum plate specification of ELROG ER845. It is named "ER284" after Western Electric 284 (a tube made of molybdenum plates and with characteristics very similar to 845).
The biggest practical point is that ER284Same parameters as ER845It is made as. 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. The charm of this ball is that even the parts you can't see are covered.
In terms of appearance, the molybdenum plate emits light, and the ER284 has slits in the plate, which allows the filament light to escape easily, giving it a stronger appearance of light. It is said that when the plate voltage is applied and the operating temperature is reached, an orange glow can be seen.

The purpose of choosing a molybdenum plate is to make a ball like the 845, which has high voltage and high loss and heat is applied to the plate, sound more stable. There are three benefits you can expect:
-
The structure does not easily shake due to heat, making operation more stable.: The plate does not easily deteriorate even in high temperature ranges, and the condition between the electrodes is easily maintained.
-
Direction where the sound image is less likely to collapse even under high load:- When pushed with loud volume or thick low frequencies, the contours and spatial organization are easier to maintain.
- Easy to maintain condition during long-term use:- By choosing materials resistant to thermal stress, it gives a sense of security assuming continued use.
In one word, the value of choosing a molybdenum plate is that even when increasing the scale of the 845, it is less likely to fail and can continue to play in a solid state.
