possibly the stock microphone has a ratio of 1.8:1
in version E we have 2:1 and a higher ohmic resistance of the primary Rdc1, so yes, we can lose 4 dB

so do you still think E wiring is (one of) the best solution ? I still have "enough" audio level anyway...

Is the polarization voltage of the capsule good?

from memory (I tested earlier this afternoon) yes ! we got more-or-less : +57v & -57v

If you configure the transformer in version A, then they will probably sound close in output level

 

[Emmathom]

Just did a quick test just to check it was working... but I feel like the sound is "more soft" than the original one, a bit less "brillant" (must do some real tests to confim)

 

[micolas]

But how is the sound quality? Does it sound as good as the stock mic or slightly tonally different?

this is good, warmer, stock is too bright

Here you have already perfected a mod for SC1100 / Z3300

 

[micolas]

check the phase, with both microphones, close
If the signal is cancelled, they are in antiphase
If the signal is strengthened, the phase of the modified one is good

 

[micolas]

You must also test the connection in version A
and compare which sounds better.
Slightly different output volume is okay

 

[Emmathom]

- the phase is good
- the sound is the same but it's more 6dB I've lost (I just did a qucik recording of speaking in my DAW, mics close to each other, same gain level)

edit : seems to be -5dB no it's really -6dB !

It is possible that Monacor, has a lower yield, or other components make the difference.
Lower hFE at A1015 or jFet with higher Idss.

Test the version A !

@Khron knows that you can't really trust the specifications published by the guys in suits and ties from the marketing department.

Anyway, I made it very clear that the transformer in the SC1100 / Z3300 is very good.

why not trying to re-put the old one ? maybe there was another problem, solved by the remake A to Z of the audio board...

Yes. Put it back. Nothing bad can happen.
You're already thinking in a DIY way

 

[micolas]

Have you tried version A though?

No... because my son needs me now : I have a family life and now it's dinner time...
I follow your advice and stop until tomorrow morning... but...
I'll be back !
Thanks +++++ Micolas & take care

Bon appétit!
Une soirée agréable!

Thank you Micolas, same to you !
PS : I'm gonna try to replace the 4,7uF tantal (C4) by a Muse BP...

ok, compare which sounds smoother
In vintage devices you find a lot of tantalum

a 4,7uF PIO won't fit in the body ! never !
PIO will be maybe in my (future) tube mic as coupling-cap...
