I found my LCR meter and confirmed that C1 is 15nF but also found C2 is 15nF (I accidentally broke C1 in the process so it's a good thing I got a measurement first). I think I'll need to get tweezer

Finished the build today. With my Tascam 70D putting out 46,5 to 47V and the Simple P48 made of 68kOhm resistor and 4,7uF cap I measured 8,2 to 8,7 V across the capsule (with some background

Yes, this much I know. Thank you. Pawe? >

These caps are bound to be electrolytics. A film cap would be way too big. As to the "low ESR" part, it's largely irrelevant. Low-impedance is meaningless.

Jack. I'm aware of the size factor, thank you. The ones I have easily available measure 5x7 mm. These should fit. As for the mics' variations - from what I gathered from datasheets I there are two

The more important factor is package size if you want to squeeze it into an XLR. There are some nice miniature sized ones around. One slightly off topic question - which particular type of AOM-5024

Thank you, Jules! Best regards Pawe?

You most likely won't hear a difference. Low ESR "Equivalent Series Resistance" on an electrolytic capacitor is one measure of the internal resistance. It is most applicable for caps used in power

OK, let me rephrase my question then. In the supplier's online shop I found two similar caps described as follows: - 4,7uF, 63V - 4,7 uF, 50V, low impedance, low ESR. (The low ESR part I just found

Low impedance capacitor does not make sense either. At audio frequencies, teh impedance of a capacitor is directly related to its value. A low-impedance capacitor is thus a high nominal value one.

Jerry. Of course it doesn't makes sense - I made a silly mistake. It should be low *impedance. * I got distracted, someone was talking to me while I was writing, I'm an ignorant fool... Take your

This makes no sense. There is nothing like a "regular" capacitor. Capacitance is dictated by the circuit. If a "high capacitance" capacitor is needed, taht would be indicated by its value. For a

Here is our Reference doc on this: /g/MicBuilders/files/Ricardo/SimpleP48 Ricardo has done an excellent job of going through all of it. The short answer for your question is that you

Good day everyone. Thank you for letting me join the group. Really fantastic reading and great people. First my question: does it matter what kind of cap is used in the Simple48? I mean - "regular"

Forgot to mention the pogo pin. The closest match I was able to find is this one:?https://www.aliexpress.com/item/4001294383416.html?spm=a2g0o.cart.0.0.fd0238danIFNlV&mp=1 . (M1648 version, 3.0x18.5

I have no personal interest in knowing the actual values of the capacitors as I'm not going to modify the original circuit anyway. But for those who want to do component swaps, it would help to know

Looking at the schematic, components used and the capsule size. I can’t see how published spec of self noise is achieved. Best Regards, Jules Ryckebusch

Has anyone measured an SC140 to either confirm or deny the 9 dB self noise?

Thanks for the verification and tips. I attached the updated schematic. I don't have a tool to verify zener diodes yet, so I only saw the forward voltage drop of 0.7v. Looking at getting the cheap

Another thing that struck me: C1 and C2 do not have the same value. In an impedance-balanced circuit, I would have expected them to be of equal value. I am not going to remove the SMT caps from the
