Re: {Collins} SM-2 mic gauze



I wonder if the filter used in a bathroom faucet would work? Depending on if flat, not conical, the dimensions some larger kitchen faucet filters may work...
Just thinking outside the box..

RCA used voile which is an unsized cloth made from cotton or a blend but nylon or rayon will work as well. If you have any of the original material you can take a sample to a Jo-Ann or other fabric shop and find something similar.  The idea of the hard weave is that fluffy cloth tends to block high frequencies.  Some manufacturers, like Electro-Voice,  used stainless steel mesh. I don't know of a source for this but usually it does not disintegrate and can be straightened.
