Mounting my Eden wt330

    Hello, new to the forum. Kind of a long story, so please enjoy if you like long stories, and I apologize if you hate long stories.

    I purchased a new David Eden WT330 fifteen years ago (in 2002). I've always had a 2u rack case for it, but never bothered mounting the amp because I never had rack ears. Recently I've been using a rack tuner (behringer btr2000 - not a great tuner by any means, but hey, it was free), and needless to say, the rack case doesn't have enough room for the tuner in addition to the amp. So I purchased a 3u gator rack bag (Gator grb-3u). So, now I would like to mount the amp and the tuner in my new case. Because of the shape and size of the amp, there are very specific rack ears for it. This isn't a question about where to find rack ears - I have already scoured the internet and even emailed Eden directly, and they are impossible to find. What I would like is thoughts on if this idea will work...

    I purchased this Gator grb-3u:

    RACK%20BAGS%20.


    After researching all day, I discovered that the WT330 is the exact same amp used in the Eden CXC110 combo, which can be detached from the combo speaker with four mounting screws located on the top of the amp (a visual inspection revealed four threaded holes on the top of my amp too) So, I believe, that the four threaded holes on my amp were designed to be used to mount the WT330 to the CXC110 combo speaker, so long as the bolts aren't too long to damage any internal components of the amp. So I figured I could mount the tuner in this shelf:

    175036_ARS1_Odyssey_main. ...


    ...and then because there are four factory mounting holes in the top of the amp, I could drill holes in the SHELF to correspond to the four threaded holes already on top of the amp, like this:,


    Du3NI4S.


    ...and then using bolts (which I purchased yesterday) I could mount the top of the amp to the bottom of the shelf, then use the shelf to house the tuner above the amp in the new rack case. So the amp will be on the bottom, mounted to the shelf above it, and the tuner in the shelf.


    The rack case came in today (the shelf and bolts come tomorrow). I loosely placed the amp and tuner in, and there is a very small amount of space (maybe 3/16 to 1/4 of an inch) between the two components for the shelf to fit it. I couldn't find any info about how thick the metal is on the shelf, so I guess I'll find out when it comes tomorrow. One problem is that the shelf has a small lip on the front, but as far as I can tell the lip isn't welded up, so I'm sure some heavy duty pliers and a vise (or clamps) can fix that problem.

    For fastening the shelf to the amp, I bought short countersunk machine screws to minimize the amount of space the screw heads take up, and am planning on drilling the holes into the shelf at about 1/32 of an inch bigger than the mounting holes (but still much smaller than widest part of the head) so that the screw head will "sink" into the hole a small amount but still have enough of the head for quite a bit of a grip, if that makes sense. I think by doing it that way the countersunk screws will create smaller "bumps" on the top of the amp than round, pan, or hex screws would, but still allow for sturdiness (but I haven't actually done the geometry and physics, and I'm not a professional mathematician or machinist lol). But like I said, there is about 3/16 to 1/4 of an inch of room to play with for the shelf and screw heads.

    So, the shelf holds the tuner, and they both mount in the regular rack mounting holes (in the top slot). Then because the bottom of the shelf is mounted to the top of the amp, it will keep the amp securely in place so it won't slide around under the shelf. In other words, mounting it to the shelf keeps it in place.

    I don't think there will be enough space to create a gap underneath the amp (in fact there may be too LITTLE space for this all to work). If there is a significant gap that is causing problems (like the shelf bowing down due to the weight of the amp), I'll just put some kind of spacer below the amp.

    Does all of that make sense? I’m sure there’s something I haven't thought of, so feel free to comment.

  2. I've seen a couple of people shelf mount items with a lot less forethought than you have shown. You won't know if there is a gap until you get the shelf and mock it up. I'll hazard a guess and say you'll need a couple of thin rubber stick-on feet. Either way, it should work with minimal hassle.

    From someone who's done a number of DIY projects, and just finished a pint of lager, it sounds like it should work.

    Very well thought out!

    On a related note, I recently bought a set of rack ears for an old WT550 from an awesome online store with an amazing selection of pro sound gear, and a name that's totally escaping me right now. I know totally helpful, right?

    On my 7th Guinness, but...

    Welcome to TB brutha!

    I fear if you try to fold the lip flat, or fold it in, you're going to end up with a buckled shelf. Most of those types of shelves are fairly thick, bendable, but thick enough that it's tough to make a fold, much less an unfold, with hand tools. I think your best bet is to move the amp back a hair to leave the lip in place and/or grind it down a bit.

    I hope it works out well for you!

    Thanks for the suggestion! Fortunately, the shelf did not have a lip. So, problem averted. Finished up the project and posted a slideshow in a new thread.

    Very nicely done!
    I found the store I mentioned, Full Compass. They've got just about every pro-audio thing anyone would ever need, plus some.
