Grade of the tube

The physical characteristics of the tubes themselves have a huge impact on how long they can last.

The mode of use is also key because the more you use the mic heavily for long extended periods, the more it is likely to your tubes will last only for limited amount of time.

It’s not all the time that your tubes will just stop working, sometimes you’ll just notice a change in the way that they sound.

How you handle your microphone will tell a lot about how long you’ll stay with it.

Tube Microphones require you take into account the tubes them selves.

If microphone tubes aren’t handled well, they’ll most likely not last that long.

Room conditions

Room conditions matter a lot.
