For the lack of this capsule that @kingkorg reccomends

I bought this one (prompted by @pasarski recommendation)
https://www.aliexpress.com/item/1005006970192646.html

I paired it with OPIC circuit by @rogs .
At first I planned to buid it the way real men do - rogs' way - on stripboard. But it lost, pricewise, to Mic Sharf's pcb. 5 USD for 10 boards is hard to beat. Sorry, @rogs 😉
Beautifully simple circuit, the build was a breeze.

The effect is spectacular - this thing is quiet. Like really quiet. The most scientific trial I could quickly run: quiet night and DR-70D turned all way up, +63dB, all I could hear was distant hum of traffic.
On par with AOM 5024. Not that sensitive of course.

Sure, not as ambitious a build as a tube mic but this is what I wanted - a quiet, cardioid electret mic.
We'll see how cardioid really it is.


BTW the pcb fits the BM-800 body. I'm not a fan but well... If it works it's good 😉
