ZX450 rail cap part #
ZX450 rail cap part #
I searched and only see part numbers for the rail caps in the MS amps (which are too big) or the or the 16 v2200 uf caps (which are not the rail caps). Anyone have a replacement/upgrade digikey part number for the 50V 2200uf ones? The tops on mine are bulged out. Thanks.

Thanks man. They are approx. 24 mm diameter(15/16") and have a height of about 27 mm (1 1/16"). They are 50 V, 2200 uf but of course I would like to add more if size permits. I could go 3/8" taller since I have the height available.

I also forgot to ask, what is the lead spacing (distance between prongs mounted to the board)? Are they snap-in type capacitors (only way to tell is by removing one)?
The most important specs are voltage and diameter. Capacitance can easily go up. We also want to make sure they are good to 105*C or more, since they are in an amplifier.
So we go to digikey... search for "Aluminum Capacitor" and click on the link. Then it gives us all the variables to fill out.
- Under voltage, we pick 50v. I click submit at this point as it greatly narrows the number of criteria to pick.
- Operating temperature, control-click on all of the options that are 100*C or higher.
- Under size, ctrl-click on all the options that fit. I can't seem to find any 24mm capacitors, but there are lots of 25mm ones. It is important to use a set of calipers to measure this accurately!
Now I am guessing it is a snap in capacitor, since most rail caps are, and that's also all that shows up in the search results. In a 25mm width, it looks like the lead spacing is most commonly 10mm, so I am guessing that is what it is as well. In that case these seem like the best replacement:
25mm height: http://search.digikey.com/scripts/DkSea ... e=P6677-ND
30mm height: http://search.digikey.com/scripts/DkSea ... e=P6679-ND
30mm height: http://search.digikey.com/scripts/DkSea ... 38-1497-ND
35mm height: http://search.digikey.com/scripts/DkSea ... 38-1516-ND
Now I am personally a fan of Panasonic caps, so the second option is probably what I would recommend. While the biggest Cornell capacitor offers more capacitance, it also has slightly higher ESR, which means it is a "slower" capacitor. Not sure which would be the best overall for sound quality, but I doubt you would be dissatisfied with either.
Make sure you double check all the dimensions before buying them however!
Also you might want to PM dbincognito, since I think he has done a few of these amps before.

THANK YOU THANK YOU. YOU ARE THE MAN. I am going to select the 2nd one (Panansonic 3300uf). Normally I would not worry about these but since they are bulged out and I know this amp has had a hard life, I am gonna replace them while recapping. I have recapped a few 2125's and 450's before so I should be good to go. They are already disassembled.
Thanks again man.
Thanks again man.
