nearly complete stereo UCD400AD's (pics)

[cowanrg]

ok, finally, the cases are almost complete... the faceplates should be complete today or tomorrow. im just waiting for the call from the powdercoater. (they are being coated in clear matte powder). here are some pics.

the details are (each chassis):

2x UCD400AD's
modified onboard caps, upgraded to panasonics
modified output cap
shared power supply (forgot cap size)
dual bridge rectifiers
shared single 1.7KVA transformer

the case gets pretty warm when listening at full volume. just kidding. its always ice cold.

another:

(they are 8" tall, 17" wide, and around 16" deep. each chassis weighs in at 65 pounds)

Impressive heatsinks - they'll take some dusting though.

 

[cowanrg]

well, yeah, they will get dusty. it wasnt my prime concern when i built them though...

i was more concerned with the "mine is bigger than yours" phenomenon.

 

[v-bro]

whoa!!

Yours is bigger than mine!

Could be because I concentrate more on building it smaller...

Unnecessarily big heatsinks, a shame to waste them for a class d.

 

[KeithC]

Good for defacing Readers Digests though.

And they ain't likely to get knicked.

 

[v-bro]

At least you get the 'Aleph" look...

thanks for the support

they aren't wasted. some of us just get to do what we want and dont care what other people think.

 

[cowanrg]

i just got the unnecessarily large faceplates back from the powder-coated and put one of them on. the meters still need to go in though.

 

[cowanrg]

they are a bit darker in real life, the flash just makes them look very light.

Why waste? No more than any other casing - me, the closest I've come to encasing a class D is a Tea Tray.

Besides which, they probably make good aerials for tx'ing any rfi.

This heatsink is a waste.

 

[Daveis]

cowanrg, where are you getting your metalwork done? where'd you get those monster cases?

I'd be inclined to put a multichannel mini-aleph into those myself.

This heatsink is a waste.

Does form have to follow function?

I think they are very decorative -- powder coat finish is nice too.

Is that a Peranders DC filter and softstart? And any chance of sharing the PSU schematic???

haha, thanks for the constructive criticism. lets see something you've built so we can talk bad about it...

thanks!

i didnt build these to impress anyone or to make anyone else happy. i built them because i wanted to, and when i go into my listening room and look at them, it makes me happy. i have some fine looking cases. i could have just done a stamped steel case with a plain faceplate, but i didnt.

yes, thats perander's dc filter and soft-start. the PSU schematic is simple enough, nothing fancy, just some caps, bridge rectifiers, and thats about it.

You can talk bad about anything that I build, since is your true opinion and is based in something solid.

Example, why a class A heatsink on a class D amp?

I'm not fighting against you, relax man...

Because it looks cool, and nothing else
