"Dynamic" mics do not have 48V phantom power.
Only condenser mics have phantom power.
But both are professional mics with XLR socket under it. The same XLR is on my digital recorder:
Yes, this is a combi socket. XLR with big mono phone plug (big, mono) in center. But I have and use XLR cable. I think, XLR cables are better shielded as phone jack cables.
This is my recorder:
This i not a "handheld", this is for "wearing" with a shoulder strap.

Has Konstantin Raudive used supply voltage?!?
There are circuits with "22pf" or "2000pf" capacitors (# 2 and # 3 in photo from book). These need supply voltage, "phantom power", or? 48V?

Is a circuit with the use of phantom bower better than one without?

The cheapest dynamic mic with XLR I found, as example:
(can you find a cheaper mic?!)

And for example, the cheapest condenser mic:

I am not searching for ready made Raudive-Diodes.
Simple versions on ebay for expensive ~$50 o_o.
"A good business", maybe I should build more fpr selling ;-) .
And a little bit soldering is not the problem.
Therefore, the question for the best working circuit.

But only replacing the microphone capsule? Hmmm, very simple.
Does not a coil belong in the circuit?
On YouTube there is a USB mic with diode etc. inside, and a litle wire (as Antenne) from inside out (!) on the top of the basket...
