>What does it do?
It lifts the GND level of IC4 and thereby the Vgg output (pin 8) for the BBD supply voltage in case IC3 is not manufactured by MEC. There's a hint in the datasheet (pic).
>does that diode affect the sound?
Not directly, it belongs to the digital side that clocks the BBD and ensures proper function. Be the first to try it out!
