anode voltage level and influence on the sound

[commanderberti]

hello everyone, the B voltage for common radio microphones is between 120 and 210 volts.. depending on the PSU.. do you have experience of how the voltage affects the sound? with an ecc83 and alternatively ecc81. How badly does the quality of the PSU (anode voltage and heating voltage) affect the sound? does stabilizing the B voltage with additional capacitors and semiconductors improve the sound?
