Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

RE: Switcher Filter

The potential issue is IMD. When two frequencies mix in a not entirely linear device (like a tube), sum and difference frequencies are created. Those frequencies can mix again in never ending combinations with harmonics of the original frequencies. These spurious frequencies are known as intermodulation distortion products. Their audibility can vary considerably with different source materials, speakers, specific output tube, etc. Regardless of whether you hear it now, it's good practice to minimize the potential for this effect.
