If it isn't a PVC diaphragm, this is a good thing because it bakes moisture
out of the capsule and keeps it nice and warm.
When B&K went from tube to solid state electronics, their earlier solid
state mikes had resistive heaters to keep the capsules warm and reduce
problems in humid environments.
If it's a PVC diaphragm, it bakes the plasticizer out of the diaphragm
as well, which is very bad.
