Mresist Ultra 47 Ohm 3-30W
The Mundorf MResist Ultra resistors are based on the well-known good tonal properties of copper-manganin foil which provides an order of magnitude lower inductance. Copper is significantly softer than the metal-oxide used for MOX resistors. The natural resonances of the copper-manganin foil are therefore significantly less pronounced, which means that distortions caused by crystallurgy and electroacoustics are significantly reduced here. Rated 3W without heat sink or 30W with optional heatsink added.
