The current tube I'm using won't even start to make sound until about 40 seconds after turning it on. Then slowly the sound changes for another few minutes. |
You may very well be right - but then, it still comes down to what tube modern mic manufacturers select for their product - and this is influenced by the fact (I imagine) that they're going to get both reviewers and amateur musicians who are just going to plug the thing in and expect it to deliver it's best sound after one or two minutes.
It's my feeling that their selection of tubes would tend towards the ones which colour the least over time.
