Capacitance increase ?

[Patrick620]

I'm getting ready to recap my Soundcraftsmen PCR800, which is doing seems to be holding it's own at running my RSII's. I will upgrade the amp at some point, but for now, and for future use with another set up, I'm gonna go ahead and recap it. The original power supply caps (2ea) are 11000uf 75V. I found a good price on some 15000 80v or some Adcom 22000 100v. My question is will 22000uf be too much of an increase? Also, is there any relationship in the capacitance and an amps ability to handle impedance dips with some speakers (RSII's) Thank you for any input.

The 15k 80v sounds like the ticket. You might have current inrush issues with the 22k.

10-15% over OEM would be OK . no more for above reason

I think I would probably go all the capacitance you can add, your limiting factor will be the physical space. Then look at upgrading the rectifiers to something beefier to handle the inrush current. Bypassing the filter caps with some polypropylene caps is a good idea too. (I use 1mfd bridged with a .01)
