Geez.That's not good. Who is smart enough to know what the cause could be?

While this thread is going - what's a good replacement foam? I went looking for air conditioner foam (as was recommend), but found stuff that was too thick. Maybe someone has a link?

I almost felt like I called the wrong place until they said they'll check with the guys in Germany and get back to me. They never did. Maybe I should try them again.greg wrote:Otherwise Mcmaster, search for the thinnest Reusable Polyurethane Foam Air Filter.Thanks! I found it. For future reference, it is this one. Catalog number 9803K301. By the way, is there any difference between 30 and 60 pores?

Otherwise Mcmaster, search for the thinnest "Reusable Polyurethane Foam Air Filter".

On a serious note, often it appears the thinner-than-hair wires on the capsule wired in with the humbucking coil break...rendering it useless. You can get a buzzing sound if a hair or bit of dust gets onto the large capsule face. Othertimes, well, I think it just blows.

This is a long thread, so I hope I'm not repeating a question, but has there been any attempts to characterise a working capsule? Or do some failure analysis on a dead one? It is after all just magnets and wire, it sounds like a lot of these could be fixed with an appropriate rewind.edit: a bit more detail, I mean taking some impedance measurements at different frequencies, measuring wire gauge and calculating number of turns.

Right, it's basically to stop crap from hitting the capsule, but I don't know which number of pores will stop more crap. Is 30 pores the denser foam?
