Jan-Peter,

Any idea on the price yet? Will you be selling toroids also? Seperate?

I'm already on another way for my 2 main channels, but I have three channels to go...

Thanks,
Yves

Default one chassis

Hi Jan. So if i get a big enough chassis then, i can possibly fit all 5 into the same chassis without EMI worries then between modules? That would be my preference. Now the PSU you are referring to at your site, been keeping an eye out on it! it will be good enough for 5 UCD's or i am sure i would be better going 2 of them one for each transformer? I am going to start looking at measurements of all these things to make sure they can fit into one chassis as that would be nice. Also then 2 1000VA transformers with 40 volt secondaries, and also add a softstart and so on? Great info people. i am off to a nice start i think. Maybe start with 2 ch 400 UCD and once thats working add from there? Thanks again.

Bill

Bill,

One powersupply with 4 x BHC Slitfoils will be enough for 2 or three UcD400. You can mount all UcD400 modules next to each other if you like. Size of the UcD400 is 75 x 82mm

On the other hand you can overkill the powersupply if you like. The best is to build 5 mono channels, but that's VERY costly!

Personaly I would go for 1 x 1000VA (or 2 x 500VA) and 2 or three powersupplies.

Jan-Peter

THanks Jan. So, would i be better going for the front mains, 2 UCD 400's with a 1000VA and one of your PSU and then the centre and two rears for 3 UCD's off of another PSU and 1000VA? would that work well? I have dedicated audio power lines with hubbel cryo outlets, so nothing else on the line other than audio, so both units running off the same outlet to the PSU's! Thanks.

Can't wait for the advanced power supplies - I'd love to know the pricing!

I'm at least looking at three channels Ucd 400 with AD8620 on a single power supply with 1000VA.

For stereo I'd just turn off the centre channel UcD.

Later I'd love to add 2 UcD180's with AD for surround on the standard power supply or a selfmade one. Could become 4 UcD180 for 7.1 action. Don't know how much transformer this would need.

Jan-peter, if possible, can you already inform me of price? Thanks!

@pharsyd, seems we have the same endgame, 5 channel UcD!

Yves... yes pretty much the same project. what case are you considering? i am going the par-metal case myself. Yes our setups pretty much the same. I am quite excited about it, as i am a total beginner and love taking on challenges like this. My north creek speakers was my first endulge into DIY kit and then my tumult sub, with my EAD TM8000, the 5chUCD400 amp will top it off for now! man, this site is fantastic.

Don't know about a case yet, probably some generic aluminium 19" case.

I'd love a 17" (43cm) case but can't seem to find any
