Microphone/Radio Question

So I did something stupid the other week. After installing a new vario and a
few other bits in my Ka-6 panel, i reassembled everything and proceeded to
test the radio. When I keyed the mic on my Terra TX-720 I blew the readio
fuse. Turns out I had mis wired the Mic.Instead of having the mic hooked up
to the power on one end I had inadvertantly wired it to ground.

The radio still receives, and when I transmit I can hear the carrier, but no
audio is broadcast. I haven't had a chance to further troubleshoot the
problem.

First question. Did I only fry the mic, or did I possibly fry something in
the radio?

Second, if it's just the mic I'd like to just get the nic element since I
won't need to eplace the gooseneck. Where can I find an appropriate
(non-dynamic) nic element?

Thanks
