theChris · 3rd January 2006, 04:38 AM

this is typically my worst area in building things. i am an EE, and not overly mechanically inclinded.

what are some chassis's you've used?

Built yourself?

pics?

Costly?

Time consuming?

I've been exploring chasis options for an external crossover. My best idea so far is to go over to mouser.com, and buy a hammond aluminum enclosure, and drill some holes in it. Its gonna be time consuming to make your own, although probably not to hard if you can find some tools or a good shop.

No offense, but those Hammond's looked crappy to me, like cast-away junk for the diyer. I looked at pics of them and thought why doesn't someone make a real chassis that looks nice?

To make my chassis, I bought a used Schroff enclosure, or bought broken/nonworking items on ebay for cheap. Or else you can try a junk shop and come up with something better than Hammond. My Chipamp is a broken Kyocera CD player (bought for $20 on ebay) with a new front panel from www.frontpanelexpress.com.

You are on the right track. The chassis is usually the most difficult and most expensive part of the project, right up there with the heatsinks and xformers.

Ideal for GC's and class-T amps (and DACs.....), these are not difficult to put together!

And whatabout cooling, Nuuk ? In this case amp will have feeling like baked beef in oven...

I wouldn't know about that - I am a veggie!

For a single channel GC, you can add a small heatsink at the rear and it will work fine. That's how my original GC's are set up and they run cool.

But soon it will be possible to purchase aluminium pods through (but not from) DD. And it should be possible to run two channels of GC bolted to either side of a metal bar that is positioned inside the tube, with the tube acting as heatsink.

For class-T amps and DACs, there is no heat problem.

Try second hand stores. Old computer modem and hard drive cases,most are aluminum and can be used for heatsinks. You will need to make faceplates but the cases are from $1 to 5.

A very useful thread if you decide to have a stab at a DIY chassis:
Case and metal working

And Peter Daniel is the king of making innovative DIY chassis. Have a search for his stuff if you're ever short of inspiration...

Or these, Mapower 5.25 drive enclosures. You have to make some sacrifices but they look quite good imo!
