Telefunken ECC8100 for microphone project?

[nmark72]

Hello everyone on this great forum,
I am currently working on a conceptual project of a quality tube studio condenser microphone, which would not be a simple copy of a well-known one such as the U47 and U67. I am considering the possibility of using NOS Telefunken ECC8100. Does anyone have experience with that tube?

What is the advantage of using an ECC8100 compared to other tubes?

As for me, the biggest advantage is that I have two ECC8100 Telefunken NOS . What I could find in the specifications, is that they are very low noise and very resistant to microphonics. Their gain is significantly lower than that of the ECC83. That's why I ask the question, does anyone have experience with them? From what I know, they have their advantages and disadvantages, but I believe they can be used well in audio projects.

Common cathode? Do you know triode plate resistance?

I'm not experienced enough to say whether a tube is suitable or not, but I'd worry less about gain and more about: having the right output transformer (and load resistor) for the anode, capacitances, and grid current.
