Very nice!

I've got a couple UCD400HGs on order, and I'm looking for a chassis. I was thinking of building one myself since the prices I've seen for them so far are ridiculous. So let me ask you, where did you get your chassis and how much did you pay? Are those 19" 2U chassis?

Why using so huge cases?

I got them from parmetal

http://www.par-metal.com

they are 19" 2 units.

I think they were 175 dollars for two. these are steel and aluminum. the all aluminum is probably 225 for two.

they need to go into 19inch equipement racks. its for my recording studio.

and it was easier to build it when I had more room inside the case. some builds of these amps I've seen were so tight in small cases. I prefer a more substantial case.

Very neat! Well done!

Wow, that appears to be from the same guy I bought my transformers from. http://www.toroid-transformer.com/ look at contact email, @ango.com, now go to ango.com and you end up at par-metal.com!

I'll be cramming two of these amps in one of those chassis as well as some other goodness.:)

the fax number is the same for both places as well. Par Metal is located in New Jersey. And I am in NYC so its right next door. the fit of the cases were good. as well cosmetically good. If I were to build it again I would get the all aluminum cases. So I can just mount the amp modules to the bottom as opposed to the aluminum face plate like I did. but it actually looks kinda cool to be to have the four recessed screws on the front plate. So it all worked out.

I think I will make the same thing again soon but 2 UcD700hg mono blocks.
I want to bi-amp a pair of Nautilus 802D's.

Or I would guess the 700hgs could easily run the N802d's fine by themselves.

What other goodness will you be adding to your UcD build?

Congratulations.

I'm not bothered by the "big" boxes, but by:
a) unnecesary long cables (power, signal, speaker). Better mounting the module on back or lateral wall.

b) lack of vent holes (maybe it's me that I can't see them) on bottom of the case. Holes up and down the box + vertical mounting of the module help convective cooling of the parts. Check the different parts T.

Enjoy,
M

If I touch the front plate where the module is mounted inside its just warm even playing at loud levels for hours. It seems pretty efficient. I had planned on driling holes on the bottom. I think I will because I really just forgot to. I left the cables a bit longer because it was easier that way :-)

currently they are on the side on the floor next to the speaker stands. so I guess convection is working in this orientation.
