Eehe... hope that you don’t take it too seriously. It’s mentioned as a little “teasing in a friendly manner” (if you know me).
Speaking about lacking of time… several of my DIY projects are delayed because of that.

We look forward to seeing these builds.

I have finally finished mounting the knobs into the new .5" bearings and 1/2" stainless shafts into the front panel. Using 2 ton epoxy turned out to be the best solution. There is stronger epoxy out there, however I'm not going to spend any more time on that. The volume knobs move smooth as butter and are very rigid within their rotational axis. I have to re-polish everything on the front panel and then I can start building the amp single ended until I have all of the parts for balanced configuration.

I have lots of parts but no case solution yet. I'm trying on an old Pioneer tuner for size. It is 9" X 16". I would have to mount the transformer to the side rail because the case is not tall enough. I will also have to stiffen the bottom and back and do something clever with the front. What do you think?

That hot huh? I was actually planning to get some steel to replace the particle board bottom and back if I decided to use this. My biggest concern is that I wouldn't have enough separation to avoid the hum woes. The other issue is that I might spend so much time and money on this scrounged up case that I might as well spend a chunk of money for a good commercial case to begin with. The HiFi2000 cases look quite nice but I imagine they would be overly pricey including shipping. Probably best to go back to the wood frame idea like TimmyMac and BottleHead but I'll have to source a good top and bottom plates and make some ventilation. The vented steel top is the best thing about the Pioneer case. I don't want to make a silly pattern of drilled holes. I don't find that too appealing a look.

You didn't see the tongue? Ha! No, I didn't take it seriously at all, and I do know you. But it did get me to thinking about what I've done in the last year: CKKIII, Alien DAC, Dynahi rebuild, and turntable gut and rebuild, bought a house. Guess I had more time than I thought. Still, though...I want more.
And back to the Bijou: I am solidifying my case design, made a few sketches, done lots of googling. I think the outward look of the unit will take me longer than the build. And I'll leave that as a tease.

Finished polishing the front panel and volume knobs. How are the other builds progressing?

Edit: would like to buy this milling machine...........

I'm still exploring avenues for casing. I thought about saving money by scrounging something, but haven't found anything appropriate and nice. I thought about spending money on something pre-made but haven't found anything I like. So it looks like I'll go back to the original plan of a wood frame with metal plates top and bottom. Where do you buy appropriate gauge aluminum sheets (and then some thinner stainless or copper for shielding)?
post #2275 of 3977
I'm thinking along these lines for casing. The frame willl be around 1/2" wood painted, lacquered and polished. The top panel will be 1/8" aluminum, not sure about finish yet.

Edit: V-Div, just noticed you're near NYC. Cool to find a fellow Bijou builder in the area!

^ That's hot.
post #2277 of 3977
That is a very nice case... should that be too ambitious, there is the NABU. The plastic front panel is removeable, to be replaced with wood or metal. It is the case in my Millett Max link in the sig. Dirt cheap, and built like a tank.

Hey MoodySteve, nice layout. Is that a graphical rendering or an actual amp? That is my basic idea too, although I was planning to have a polished aluminum top plate. The painted top looks good too.

Maybe we can compare our end results at an upcoming local meet.

It is a graphical rendering done in a 3D CAD program.

I'd love to compare the two amps, as I'll be using a slightly modified BOM and circuit (Regal mod, probably Amphead mod). Are you building it totally stock?

Regal Mod, Amphead Mod, Rubycon for C5, Sonicaps for C1 & C6, attenuator for volume control, eventually the 6H30 mod.
