Default New enclosures for DIY

We manufacture custom sized aluminum enclosures for DIY projects. We can currently make enclosures 2.25, 3.25 and 4.25 inches tall. The width and depth are configurable in 1/32 inch increments between 4.5 and 24 inches.

We make each enclosure to order. Let us know if you need something special.

For more information, please visit our website or ask a question here.

Also, Pete Millett started a thread with some info and pictures of his amps in our chassis:

New semi-custom metal chassis manufacturer

We've started this thread to support discussions and answer any questions you may have.

Hi Dave -

Just wondering if I painted the chassis would I have a problem with assembly. It all looks fine except for the countersuck top plate.

Awesome job and thanks for a Hammond alternative!

Send us an email when you place an order to let us know you want the top and bottom plates cut undersize for painting. We'll cut the lid about 0.010 inch under in each dimension for 0.005 extra clearance on each side. More or less if you prefer. Just let us know.

We realize that we don't have a comment field to use when placing orders so we're adding that to the shipping page. You'll be able to note your preferences there.

We now have perforated sheet and can provide it as a top and/or bottom for any of our enclosures. It's 1/8" thick like our other top/bottom plate material. Holes are 1/8" on 3/16" centers in a staggered pattern. This gives an open area of 40% for some good ventilation.

The perforated material is aluminum alloy 3003-H14. The extrusion and plate we use are aluminum alloy 6061-T6. The two will look a bit different when anodized so you may want to leave the perforated sheet as is. It has a nice smooth finish on one side.

Excellent. I was thinking about the bottom cover for the perferated sheet. I'm slow at finishing the design, but working on it.

Now just figure out how to make some transformer covers and you have it all!

Another option for bottom ventilation is to use our corner plates. Granted these don't provide any protection from harmful voltages that may be present inside, so be sure your design is safe enough to use them.

As for transformer covers, we can make enclosures as small as 4.25" x 4.25" and as tall as 4.25". Might be a bit pricey for the use, but it's doable. Just pick your size

Nice website Sandy. Lots of cool stuff.

The open bottom is not an option as I have kids

But I Have been looking at some interesting ways to make a box for the transformer covers. I'll come up with something as I really like your chassis flexibility and pretty sure you could come up with something simple that would match.

One quick question what is the size of the top/bottom edge/flange on the chassis? Getting close to a fixed PCB size and want to allow for the edge so I could lift out the top plate as a complete unit.

Sandy,

The flange is 1/2" wide. I just realized that we don't have that dimension on our detailed drawings. We'll add it.

Thanks

I am the new owner of the shiney metal box shown in post #5. Dave at Landfall Systems worked with me to get this designed, and acquired the perforated aluminum to create a rather unique rack or cabinet mountable tube amp design. Plans are underway to create similar chassis for the SSE and TSE.

I did a mock-up of the completed amp to make sure my thinking was correct. Pictures are in post #23 of this thread.

New semi-custom metal chassis manufacturer

Once all the parts have arrived a new thread will be opened in the Tubes forum to follow the build. The Edcor OPT's are several weeks away. They were just ordered.
