In the Cornet 2, C202 is specified as 0.047 uF 630 volt
Does the voltage across this cap really get that high? Would a 400 volt P-I-O cap break down in this circuit?
-
Electrically 400V is OK, but I'm more concerned about capacitance precision and probably how stable the PIO will behave in the position.

Yeah I know what you mean; you can get 2% tolerance film caps, most PIOs are 10% or 20%. I have some Russian NOS 0.047 uF PIOs, they measure like 0.055~0.058 uF. Not good for an RIAA filter.
I have some Sprague 0.047 PIOs they measure 0.046 ~ 0.049 but they're only 200 volt parts.

You can probably get away with 250V caps in that location, but use 400V to be safe.
