Might get you a few less ohms when fully exposed for the same mA. Keith,

I don't think you can an ever get zero volume though, as it would need the photocell to be a zero resistance. With human hearing being logarithmic you would need to get the resistance very close to zero for it to be below the threshold of hearing. Chris Hi Keith,
