A weak distorted sound is exactly how I would describe it.

This is new to me and I would love to hear the theory behind how a rectifier tube could affect the sound quality.
It will only affect sound quality if it has low emission resulting in low B+ voltage. Some audiophiles with more money than sense will claim to hear an audible difference in rectifier tube brands, but they also claim to hear a difference in power cords, spending over four figures on them.
I’m not doubting it I just don’t know enough to understand how this happens. As I far as I know the 5U4 creates a voltage needed in the amplifier, this tube has no gain qualities and if it’s good the voltage is there, if it’s defective there would be no voltage and the amplifier wouldn’t work.
Mostly correct, but low B+ voltage will produce weak distorted sound.
