Well yes, there's that!

I would love to get this amp playing before they get here. I have an F4 and Aleph J in the que, too.

Twins? Yes, get something built and working before they arrive. Your DIY time will go to ZERO for at least a year...

But aside from that, Congratualtions!

10,000uf - ECO-S1VA103CA Panasonic Electronic Components | Mouser

Which one you use is dependent on the final PSU configuration, I.E., how many capacitors you plan on using.

If you are going to use the chipamp.com PSU board, with one transformer and PSU board per channel, you may use smaller caps.

But, this is DIY, and complete and utter overkill on the PSU is de rigueur...
These caps are not available anymore. Could someone please point me to another suitable 15000uf cap from Mouser? Thanks in advance!

Thanks Joca and Attila!

Does the SLPX153M035E7P3 cap look to be good? I think it is the 15000uf version of the above cap.

Or am I better off with 380LX153M035A022 or 380LX153M035A022?

hi giantstairs,
the united chemicon caps seem better. (less esr & more ripple)
plus higher voltage - meaning longer life.
