Or, you have simply built two stunning stereo amps.

Creativity and simplicity, I love it. You still have to make a casing for the modules and we are on the edge of our seats.

And very good pictures ! Bravo !

thanks everyone for the kind feedback.

those cases are custom made - concept to working power supply took the better part of 3 months. i enjoyed every second of it.

here is a link to my google gallery that shows some of the construction steps:

i was going to put a case around the amps (modules) but i have grown to like them open. Presently there are more pressing projects which i hope to post here soon. however, i could be swayed to put a case around them if that is a the consensus of forum members.

suprehkm your "creativity and simplicity" comment is the ultimate complement as that was exactly what i was aiming for.

Beautiful work. Truely a Peter inspired design...

A case would close up the low voltage points on the amp modules, but I myself would just mount them to a board / metal from below so they didn't fall over. Make it a sorta amp stand looking shelf but secretly it would be an intigral part..

But again, gorgeous work...

Very nice.

I would prefer the amps in the same style case as the PS, though.

How much did the aluminum cost?
