    Anyone replacing caps?

    Anyone replacing old caps in their amplifier power supplies? I have a handful of nichicons that I plan to list on eBay but I figured I would check here first, see if anyone needs some.

    I'm currently holding on to some 50v 4700uf nichicon, and some 35v 10,000uf CDE caps. I will take pics and start a proper Sale thread if enough guys want them, didn't figure there were too many here that did this.

    Look like these (not my listings!):

    5 CDE 35V 12 000uF Mini Snap in Capacitors New | eBay

    2pcs Nichicon 50V 3900uF Snap in Capacitors New | eBay

    Easy mistake.

    Measure the DCR of your drivers and I will tell you what cap you need to buy for your 5k high pass, they can purchased pretty cheap on PE or the like. A single cap will only provide a theoretical 6db filter pole, FYI.

    You have 180v rails?

    Damn... big powa.

    Yeah, sorry. These are more for the usual Class A/B amps that might need the old ones replaced simply due to age. Good luck, mang.
