sounds great, the T47 (Behringer) tube circuit are perfekt für the AKG C3000 Capsule.. see the steps..

That's an interesting idea!
What can you say about the self-noise?
With the C3000b capsule, the SNR will improve a bit, but the stock T-47 had maybe over 20dB of noise with the original small electret.

With the AKG capsule SNR will improve a LOT!

That's exactly what I thought, but the headroom will decrease.

exact , i will test it on weekend.. with the c3000 capsule the output is much higher.. i will test the headroom.. and test it with lower gain tubes.. results i post here.. cu

here you can see how i mecanical fit them together..
