Thanks for the explanation, but I'm afraid I still don't understand what you are saying with this?

It is true that Neumann has a schematic version both for the VF14 and 13CW4 but not for any other tubes as far I as know.

Power supply design is a very important aspect of high quality audio. As a general rule, it is not enough pay attention only to ripple and voltage. The old and simple supply for the U 47 works great, but only problem is if the line voltage isn't right, because voltages fed to the mike will follow.
