Why do you need 160V caps? That amp should not go that high in voltage? If you really need those caps start another thread in "parts"- no one is going to see your question inside here.
Hi Guys

Just so you see the need for high voltage caps.
the nxV1200 has a nominal supply rail of 110 volts for the output stage and +-110 volts for the input and driver stage.
125 volt caps would be more than good enough if you could get them in any reasonable supply, so the next level up is the 160 volt capacitors.

Theo you might want to try this US company, they might just be able to help.
Capacitor Supply, Inc.
BTW $38.00 each for those 160v caps is not a bad price...

Cheers

Anthony

Figured the supply would be around 100V.

Hmm..... For that kind of thing check out ebay store jea capacitors. Don't buy 1 or 2, those are very expensive and you lose a ton of money. buy in quantites over 10 and you get a very very very good deal. Here is an example (sell the ones you don't need). Hey you may need a huge case after all!

42 Caps for $158

I noticed in the past that they have illogical pricing. Sometimes a single capacitor costs almost as much as their listings with 10 or more. You have to monitor the stuff they have and strike at a good set of caps. Check the date codes too.

I'd still post a thread in 'parts' and see what others here think.

Well Done IGreen!

Those caps would be Ideal for the job... connect a bunch of those in parallel
would work just fine and very cost effective.
I would use at least 5 of those in parallel per channel for the output stage.


Cheers

Thanks for the suggestions guys.

lgreen I have taken your suggestion and ordered 2 x Pesante Dissipante 4U cases with 10mm milled aluminum fronts and handles from HiFi 2000 in Italy. They look to be very nice cases indeed. A little on the pricey side at about $325 per case with shipping but certainly a good value judging from the quality.

As for the caps I've decided to stick with the 3900 uF 160v caps which I originally ordered. I found some better ones for order on mouser but got a lead time quote of 37 weeks to wait for them...not worth it.

Anyway once Anthony ships the amps and I complete the build...likely sometime in August I'm hoping to have some beautiful amp porn to post up and make my fellow forum members Jealous.

Anthony ... any news on the availablity of your Rev 2 DAC yet?

-Theo

Well,

At long last I've finished my first NXV-1200 amp build. I've got one more to go. So far my impression of the amp has been that it is very good indeed...lots of power and dead quite. Grabs ahold of my 18" sub and produces tight extended bass.

I have not had the chance to really put the amp through its paces but when I do I will certainly post my observations.
