That is what I want to know, purely for curiosity, how it can affect the sound, but in my case I can tell you it does.
Today I have experimented with the new tube versus the 2 old ones (included the one labelled low voltage). Now if the voltage has no impact, why would the amp guy who restored my amp swap it out ?
The sound with the old ones is slightly fuzzy, and increased sibilance. Just a bit out of focus, but enough to be annoying.

I think you've answered your own question. Among the audiophool community,there are people who swear that soaking a power cord in liquid nitrogen willre-arrange the "grain" of the copper and yield better sound. Well, god bless 'em.If a rectifier can produce clean DC current, it's good. A failing rectifier can let 60 or 50 Hz seep into the signal chain, but if the DC is good, that's all you canask of it.
