I know I shouldn't have been a failed servoid, because I actually believe
in diagnosing the fault then doing component level repair, not just
swapping modules until it appears to go away...

YEs, the CPU printsets generally incldued the PSU modules as well (and
sometimes memory, teletype interface (DL11) and so on).
