have a broken Marshall MXL USB mic which isn't worth getting repaired. The mic element is 32mm in diameter. Is it feasable to remove the condenser element & connect it directly into the mic input of my computer sound card?

** Told you before - no.A condenser mic capsule is nothing more than a 20 to 100pF capacitor with one fixed and one flexible side.
It needs DC polarising with 30 to 100 volts and a sensitive pre-amp with around a 1Gohm input impedance.

And in this case uses a fet near the element to get some juice going. I was starting to write capsule, and this certainly isn't a capsule. All the stuff should be allready be there minus the USB.

** The FET is no use without the polarising voltage or a DC supply.** The term " capsule" is commonly used for such things.
Just distinguishes the transducer of a mic from the case / handle, matching transformer and/or internal pre-amp circuitry.
** Shame how power from the USB is used to operate the mic........ Phil
