Hi Perry! How you doing? I have a question Sir. I have and old infinity 611a amplifier. Amp is working good and no problems I had it installed on my car but couple of days a go opened it to clean the internals usually i do this from time on time with some computer air can.Well I find that 2 capacitors are swollen so before they blew and make it worst I plan on replacing them one is 10uf and the other is 33uf both BP and 100v so I was reading this that you posted on this thread.
Hifonics mono amp with non polarized capacitors brz1700.1d
"The series caps EACH have to be able to withstand the full rail voltage. One is always reverse polarized and when reverse polarized, it drops very little voltage. Virtually all applied voltage is applied to only one cap at a time. In practice, in the amps that use reverse series caps, the individual caps are rated for 2x the maximum voltage that will be applied (2 series 200-250v for an amp with ±80-100v of rail).
I use 10uF film caps to replace 10, 22 and 33uF BP electrolytics."
Well the question is can I use a 10 uf film capacitor to replace both of the swollen caps? I see you recommend a panasonic 10 uf 250v 105° to replace the electrolitics, this same cap can be used to replace a 22uf 250v BP capacitor too? Last question is for a hifonics amp capacitor.

When the feedback it taken from before the output inductors (this amp), the amp is likely less sensitive to a difference on the filter components. I think you should be able to use 2 10uF caps. That said, you appear to have a bit of extra space that would allow you to connect caps in parallel.
Thanks for your answer Mr. babin I really wonder why is so hard to get this capacitors.if just they had it in stock (Electronics stores)that should make the life easy for all of us. So 2 10 uf film caps for the infinity should work? And 2 10UF stacked for the hifonics ?
The infinity uses one 33uF and one 10uF. on;y one 10uF in each location should work but if you can find the space to connect more than one in parallel to make up the additional capacitance, I would,
Do you also have the Hifonics?
Do you also have the Hifonics?
that should work then and yes I have a hifonics ZXR 2000.1d here at the garage same problem bulged output cap still functional. Cap is 22uf 250V 105° this cap is very hard to get.
