Even the later plasticized-paper ¡°Prokar¡± and ¡°DiFilm¡± versions can cause trouble in some applications ¨C they may not be leaky, but their Dielectric Absorption
and Dissipation Factor are ¡°through the roof¡±.

ALL Sprague "Black Cat", "Black Beauty" and? color striped "Bumble Bee" condensers should be considered bad on sight. Unfortunately, they are common in older equipment of all makes and models. The 630V. polyester condensers
are a fine replacement. The only condensers that are polarized are electrolytics, poyester condensers are not polarized.

My unit has Black Cat 0.5MFD 400v axial capacitors for C8 and C9. Would 630v polyester unpolarised caps be ok replacements?
