Thanks for any help you can offer.
Mr. Acoustat,
I've searched through my online parts providers for a 220 uF polypropylene capacitor and have only come up with a Solen 200 uF-200V. Whats the effect of going away from polypropylene in favor of a standard polarized capacitor?
Any thoughts on locating a supplier?

If you need to replace the capacitor, or would like to upgrade, polypropylene is the way to go. Electrolytic capcitors are audibly inferior, but are often used due to their much lower cost. You can always parallel multiple capacitors to achieve the 220-uF value. The exact final value is not critical: within +/- 20% would be acceptable. So even the 200-uF could be used.

I just re-read your post, and noted you said "standard polarized capacitor". Please note that if you elect to stay with an electrolytic capacitor, it must be a NON-polarized electrolytic. Polarized electrolytics are for use only in DC circuits, whereas non-polarized electrolytics are for AC circuits like speaker crossovers.
