True capacitor and back electret

[suddentwigs]

Does anyone know which popular large diaphragm condensers are true capacitors and which are back electret? Nobody seems to specify. I know the difference is pretty minor, but I am nonetheless curious. I have my eye on the Oktava MK101 in particular, largely for vocals.

True large diaphragms (1" and up) are all, AFAIK, true condensers. I don't think anybody builds a back electret over about 3/4".
