I bought a brand new Telefunken U47 from the official dealer in April 2024.
As you know, it’s a super expensive mic, so I’ve used it with extra care. There is no damage at all, and the moisture levels are perfectly controlled with the moisture control cabinet.
I used it without any problem, but today I could hear a slight but noticable noise. (It’s not a popping noise. It’s steady)
I turned the power supply unit off and on, and it disappeared. However, after few hours of recording, it occured again.

You can see the noise around 120hz
I have an important recording schedule and I’m waiting after sending an email to Telefunken now, but wanna hear your cases before I get a reply from Telefunken.
If I had bought used one, I could think it’s time to replace the vacuum tube.
However, I bought a brand new one in April!![Face with tears of joy :joy: 😂](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f602.png)
If you wanna listen to how it sounds, I will upload it too.
Really need your helps!
