nearly complete stereo UCD400AD's (pics)

cowanrg · 21st November 2006, 04:53 PM

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.

(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 · 22nd November 2006, 03:57 PM

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.

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 · 22nd November 2006, 07:17 PM

Good for defacing Readers Digests though.

And they ain't likely to get knicked.

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