Are you sure it is a back electret? Looking at the pics it seems that they might use generic SD capsule used in ML603, etc. and put a housing around, as a phase correction. Two high Z resistors on another pic might suggest it, as well.
Can you take the capsules from the housing and post pics?[/quote]
To be absolutely honest, I'm not 100% sure about the capsule, but:
It's not so easy to get out without smashing the whole thing to bits. It's glued in place, and this is still a notionally working mic. I could probably get another image of the back of the capsule closer up with care (and a bit of luck - my digital camera isn't
that great). What I
have got is an old Sony capsule that is very similar at the rear, and I've put that in the scanner:
It will be much easier to get a close-up pic of the single capsule in the C01 if you really want to see it - there isn't really anything in the way of this.
The other thing is that if we assume that Samson are sailing as close to the wind as they can get, then they
claim that the C03 uses a 3 micron diaphragm - and this would sort-of indicate that it wasn't the usual cheap sandwiched-onto-the-diaphragm electret construction, and would rather indicate a back-electret design.
Incidentally, I've tried looking at all of the usual suspects to see if I can find out who made these capsules - and so far, I've managed to rule out everybody except Lectret - whose website appears to be unavailable at present. But they are about in the right place, I think.
