Hi guys! I'm looking for some advice on replacing what I believe to be an JFET that was externally fitted to an old-ish USB mic.
Quick summary of it's life. Purhased it for gaming a good while back, found it too quiet so I ripped the microphone out and directly wired it to a 3.5mm jack WITHOUT THE pre-amp. Fine for a couple of years but then I think i had some grounding issue. Behind the mic was a small pcb about 1.5 by 1 cm with a small 3 pin component on it, which i believe was the JFET.
While cleaning up the soldering the copper came away from the pcb and broke one of the legs to this component.
The mic itself is fine I just need to figure out what the replacement part is.
Unfortunately there's no numbers on the component.
I've included a picture of the mic and a link to the actual original microphone.

Since you're the first out of many posts I've made on different sites to reply with clear knowledge, which out of those will provide the best result in terms of volume and noise?
My knowledge is very limited.
I ask because I cracked open a small condenser mic from a dead laptop to experiment. Opened it up to pull out the small board and wired it up.
It worked but the mic audio was way quiter and more noisy.
Can't quote a reply to JonSnell but it looked like this
It had no markings on it which is why I'm needing expert opinions

You can probably just buy a new mic (look for type "electret") capsule including its FET for less than the cost of just the fet.
