Blue Yeti Broken Capsules

So sometime ago i've bought Blue Yeti Mic on ebay.
After connecting it to the PC it was recognized but the mic wasn't hearing me.
So i decided to check what was a problem and took it to the Lab.  Connected it to function generator with sin wave 3KHz and heard it on PC.

So i guess problem is in the Capsules (the strange thing that is 3 capsules broke together)
Anyway i want to try and repair it.

The proble is that i don't know where to find those capsules.
it's 14mm diameter on 6.3 height.
As i also understood it have internal FET. 
On the back it have 3 connections (Drain Source and Gate)

Where can i buy it or what capsules will also work with it?
Any help will be really appriciated. Thanks and sorry for bad english.

And welcome to you. 

Where exactly did you connect the signal generator (inside the microphone)?

Are you sure? Can you post a picture?
Most 3-wire capsules have Drain, Source and ground (Gate is not accessible)

I've removed all 3 capsules (each of them connected with 2 wires and connected function generator to those 2 wires.
It was as the function generator was one of the capsules.

I'll post a pic later, but i think you might be right.
On the internet i found something very similar. I think it might be it
(tried to order it from this guy, but it's harder than i thought it would be)
