Default Heatsinks.....

Yep, these Machtron heatsinks are things of beauty....

I'm now dreaming up other (class A) projects, just so I can use more of them...!

Unfortunately, Jim--I have an unused pair I can show you, but I have them packed up already for the pending move to the Florida homestead (and I don't know which of the 50+ cartons have them....!)

But come on down, and look at my Chip Amp in person.....any time!

Ken

Normally, my first comment on chipamp builds is "Have you thought about the dissipation in the heatsinks?".

Rats!

Cracking build!

I saw this thread referenced in another LM3886 build thread so had to have a look. Wonderful job and looks stunning! I'm getting ready to start an LM4702 based chip-amp project. I'm using some pre-assembled modules, but the case and layout will be of my design. It will be based on this amp module. It's been years since I tackled anything this major, but figured I have some time on my hands now so why not.

I can't fabricate my own case as you have so competently done, so am looking for off the shelf enclosures. I've looked at a few brands online that are nice looking, but since I haven't finished the final design I'm not sure on the exact size I need. I'm still waiting on most of the parts to show up. The project may go from an amp build to an integrated amp build, so additional space will need to be considered. Plus I have a monster toroidal to deal with. Do you have any recommendations for quality enclosures?

Anyway, just wanted to say thanks for sharing your amp design and build. I'm sure I can learn from your experience. Came out looking very professional and expensive!

Thanks for the comments. I don't know about professional and expensive.....but I can confirm it's HEAVY--one of the drawbacks of huge heatsinks and a thick chassis....!

As for commercial chassis, I really don't have any good recommendations. I've discovered if you can integrate the heatsinks and rear chassis apron and base plate, it's easier to DIY than find a classy commericial chassis/enclosure.... In my case, the last "piece of the puzzle" was the front panel, and Front Panel Express provided me with the answer I was needing.

It does look heavy too! Hey thanks for the heads up on FPE. Hadn't heard of them until now. Looks interesting and useful for future projects.
