Sorry in advance if this is a stupid question.
In a tube rectified PSU that is CLCLC, I know the first cap size is limited by the rectifier, but does this cap need to be polar, non-polar, or does it matter? I was planning to use a 5uF cap I have on hand in that position, but it's non-polar and I can't wrap my head around what would go on in that case. Since one side is attached to ground, I think it would act like a polar cap. Unfortunately I don't have the spice/modeling skills to look at it (and I don't think PSUD has non-polar cap options).
BTW, I kinda need a cap input for voltage, but want to keep the rest LCLC. Any thoughts or explanations would be appreciated. Thank you!

It can be either polar or nonpolar. Polar electrolytic capacitors will be smaller than nonpolar film.
If it is polar, the positive terminal must connect to the cathode of the rectifier.
Polar is a sub-category of capacitors that require attention to the DC voltage that is impressed on them.
No reverse DC voltage may be applied to a polar capacitor. No such restriction applies to nonpolar capacitors.
