Default Differential output stage: cap voltage?

Hi,

How does one determine the required voltage rating of the caps in typology "E"?

Doesn't need to be any different to normal. I have this on an 807 amp and use 64V caps with it biased up at about 20V. Only had issues when I tried lowering the 1meg resistor to about 300R- but thats a long story that isn't really relevant.
The only thing to note is that the caps are in series and so their value is halved, but I expect you spotted that already.
