I went and looked at the sch.
If we are talking of C4/C5 (C6/C5) rectifier filters (I have Electrotanya copy, the quality is iffy), I am not sure if it shows +/-60V or 80V voltage at the inputs of the 48V regulators, at 220V version it does look both as 60 and 80, but while 80V WV is sufficient for 60V, I would bump it up a bit. If it is 80V, it is downright inadequate but, this being Pioneer, I give them the benefit of the doubt
In Telecom AT&T required us 4x for WV (read 20V WV for 5V circuit), and this is overkill (this was with redundant power supply arrangement), but my personal preference for stabilized voltages (after the transition), at least 50% margin (1.5x), better 100% (2x).
If you have bought these already, it is good too. I myself am not sure I care about the next generation using these. But when I do it, I do it for my own sense of "done right."

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
