I like the one on the far left. What software are you using to generate the illustrations? Also, do you do the wood work yourself?
Cheers,

Thank you! I didn't know the Krell bookshelf. I based my drawing in a Sonus Faber bookshelf. I like the curves on the side. But to say the thuth, I think I'll just make a common rectangular speaker following the Dave Ellis project on www.ellisaudio.com. It's easier and sounds the same. I don't have much time do build the speakers and I want it to be done as fast as it's possible. Maby I i'll build a more "cool" enclosure sometime...
Tom,
I'm using the Microstation. I'ts a professional CAD program. Yes I do the work myself, but the wood finish I will let a professional Craftsman to do because I want it to be perfect.
cheers,
Guilherme

This attenuator is a ladder type with vishay dale resistors. In my tests I found that it have a neutral sound, the pre sounds excelent. What is your suggestion?
BTW i'm thinking about changing the attenuator for a stereo pot.
cheers,

Clas A hybrid.
and here's the mess at the bottom. Tested a few fans DC and AC, this one is the least noise so far, a Pabst 120V running on 70V.
In the top corners are the Mos Fet source followers for the Mu stage, on a sort of surfacemount fashion. The components are siliconed to the top plate.

6C45 amp
This is my second 6C45 amp.
5Y3 rectifier, 6C45 single stage.
As you can see, there're PC boards
For convenient parts collection, it's based on a kit provided locally. I kept the boards & made some major changes on power supply & bias method & operation point. About 0.7~0.8w per channel, sounds very clean. It's serving 160Hz & up, I like it very much

'finished' el-cheapo amp.
My build of the push-pull 'el-cheapo' schematic (see 'bargain basement' thread on the Decware forum). One change from the posted schematic - I upgraded the output transformers to use Dyanclones. The wood base is Mahogany finished w/ Fromby's tung oil. By the way, nothing 'cheap' about the sound. It's very open and natural sounding. I started this as a fun winter project and now I can see that I'll 1) keep this amp around for a good long time, and 2) curiosity will get the best of me again, as winter's approaching and it's nearly time to pick out another project.
