I know this question has been asked a lot but I just want to confirm since this is the first time I build the crack. My understanding from all the reading so far is if I have the choke install, I can use a film cap less than 220uf. My question is can I replace all three cap with 3 Panasonic EZP-E50107MTA CAP FILM 100UF 500VDC?  I have replace the two front with these. I am attaching the picture of the build so far.

Thank you much!

Well, if you have already done 2 and have the other in hand, pop it in there and see if the supply is  quiet enough for you ...John

I will need to buy 3 more. But since they are only 100uf. I just want to confirm it would work hand in hand with the choke.

It's not a bad idea to leave the last power supply cap a little bigger.  You could put two of those 100uF caps in the last position and leave the other electrolytics.

Thanks Paul. How would I go about wiring two of the 100uf cap?  Do I just wire them in parallel?

Yes, wire them in parallel.

Thank you. I also notice some people bypass the film cap also with a 1% uf value film cap. Does it provide similar outcome as bypassing the electrolytic?

You'll have to do that experiment and see what you think.

Thanks Paul. Does this act as a 200uf?  If that is the case the max these Panasonic goes for is 110uf. So I can get 2 110uf.

Yes, paralleling capacitors adds their capacitance.
