You'll need 995uF -so, 10 100uF caps in parallel would equal 1000uF (close enough to 995).

Those FMods are actually better as they are considered active -the caps are passive.

You'll want these ones: http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=266-274 100Hz high-pass.

You can use a 50% electrolytic/poly mixture on the caps. If we were dealing with Accuton stuff and Monlithic amps the 100% poly would make sense. This ratio can be changed to more electrolytics. The Metal Polys become bypass caps. The cost difference is easy to see. The F-mods do have insertion loss and are non adjustable.
Part number 027-378 @ $7.00 (500mf Electrolytic)
Part number 027-447 @ $27.00 (100mf Metal Poly)
