You can 86 the magnets unless there larger they don't hold well at all. I'll simply screw the top down so much for that..............Bill

Maybe you can use electromagnets that don't allow you to open the amp while it has juice and don't hold the lid in place when current is removed. Or maybe just "screw it" and listen.

Rare Earth Neodymium magnets would work. If you get ones that are magnetic from right to left rather than Axially you can attach them that way very easily. Neodymium magnets have a pull strength anywhere from 3lbs-100lbs each and are relatively small and inexpensive (though not as cheap as screws).

Hey Guys! I finally finished my enlosure. I had a few finishing problems which I figured out were due to my garage being too cold. Because of this I had to redo the finishes a couple of times which always ends up looking worse than if it had taken the first time. At some point down the road I intend to pair this amp with a Dodd Buffer. Anyway, here are the pics.

As you can see it is pretty tight in there. If I weren't trying to match this so that it can stack with the Dodd Buffer I would have built it larger.

Best,
Ed

Building it is more than half of the fun and I am listening to it in another case so, what up dude

ebag4, how did you do the lettering on the front panel?

A little tight, but still a very nice job!

Hi Ed

great job

The board arrangement is similar to what I have in my "jewelry box".

I envy some of you guys. I have no problem messing around w/ the insides, but I have no idea how to build anything as remotely as cool for an enclosure...

Thanks guys. Yes, it is tight in there. To get the boards out I will have to remove the transformer first.

Regarding the lettering, that was a first time try at engraving. I first printed out a full size label and stuck it to the Maple. Then I tried using a Dremel tool but was having trouble controlling it so I ended up using my trusty multitool (utility knfe) to finish it up. It turned out OK but I think I could do a better job if I started with the knife first.

Best,
Ed

I like the look of the amp, you did a great job.
You can go back the logo with a solder iron.

Thanks Trung. I wish I had thought of/heard of the soldering iron trick before I put 4 coats of poly on the maple.

We live and we learn.
May be next build turned out even better.

Just packed up Shadowlight's ClassD amp. In the week plus it has been here, it was fun trying different tweaks to tailor the sound to my liking. And given the limitation of it not being my amp, I think I came close. Briefly it requires careful selection of wire to compliment (offset its sound-nature) its sound signature, power cables/IC on the warm side of neutral suits my taste best, it sounds better with power conditioning (see the Felix threads in the Lab circle).
When I unplugged it a few hours ago, I swapped in an Exposure 2010 amp to see how it compares, it came close but the Exposure had better (my preference) bass, better soundstage (more 3D), and an overall liquidity to musical presentation. The ClassD amp has a starkness to it, highlighting percussive notes and female voice, the bass was pretty tight but was a tad too dry IMO.
I think its a very good bargain for the sounds quality it presents.

I will be curious to hear impressions of the next version, with promised improved soundstaging.

Thank again to Shadowlight for the audition.

Is the nut driver under the Powercord your best tweak ?

Ed between your new amp and your Neo project you sir are a craftsman. Your replica's are outstanding!
