enclosures..

[Spasticteapot]

I'm working on some high-WAF enclosures that should be up for sale soon. They should'nt be too insanely expensive ($100-$200), and will include such nifty objects as panel meters (and drivers), knobs, and heatsinks.

Par-metal definitely makes some nice enclosures. I am currently putting a stereo gainclone amp together in a context engineering 6" x 6" x 1.5" chassis -- everything but the transformer fits so far.

You can buy context engineering cases at Fry's Electronics, or you may be able to find them with a google search.. I buy them locally, so I don't know anything about online retailers that stock them. They're similar to the Hammond cases, except that they're clamshell rather than a C channel with removable top, and they use a black or sliver brushed anodized instead of a flat black or flat aluminum like the hammonds.

Also, a lot of people seem to like the Lansing Instrument cases (www.lansing-instrument.com). They're on par with par-metal cases from what I've seen.

Or you can get something nice from AMT (forum member here):

I've been eyeballing the small THL audio enclosure for a stereo SKA 150 amp. I've seen the same enclosure a couple different places. Can I order a single piece from them?

Is anybody else interested in the PWAD-A40? Maybe we could get a group buy going.


Also sescom is another source of lightweight enclosures that look a lot better than a bud-box. http://www.sescom.com Their prices have been slowly creeping up so they aren't quite as good a deal as they used to be. I've got an Amp6 in one shown here:

Very nice, its going to need some vent holes for cooling...good luck with that!

Hmmm.... What you will not be able to see in the pic is that I have replaced the back panel with a slab of 12mm thick aluminium to which the chips will be screwed. I know that the valve/tube will generate some heat, but I'm not sure how hot it will get inside there.

Maybe I can drill a row of 13mm holes along the top of the heatsink/back panel? The casing can "breathe" (for want of a better description) around the sides of the front and back panels - they are not a tight fit, with perhaps a 2 - 3 mm gap at the sides. Do you think that is enough for a convection/cooling effect?

That series of vent holes should be fine, make sure to vent the tube too.

I just received my parts connection catalog and see that they have chassis available on page 267.

Oh, so the vacuum leaks out, you mean?

The tube is in the same compartment as the amp chips, so what is ventilation for one is ventilation for the other. The tube is running on low voltage anyway...

Thanks for your interest. I'll put up some pics and a report as soon as I get it together.

If you guys need any Middle Atlantic product, I can get it at near dealer pricing.

Someone mentioned it, but, I want to reiterate it: use old stereo enclosures. I wish I had saved all my old stereos, to recycle them, but I tossed them all. I have an old cassette deck that just gave up the ghost, so, now that I'm in diy mode, I'm keeping it to use for an enclosure. I can either put on a nice figured wood face, or have some aluminum cut and polished for one. Thrift shops would be a good source for cheap enclosures, and you might be able to get some from the dump, if you have one nearby, that will let you rummage around, as well, let your friends know that you'd like their fried equipment when they're going to throw things away.

Just as there is "found art", perhaps there is also "found hi fi"!

How about scouring the junk shops for interesting old boxes and stuff?

This will be my next amp enclosure - an old flip-side toaster. The volume knob will be from a Gibson guitar, mounted on the top. Happy hunting!
