Hello everybody!
I'm Peter, live in the Netherlands and i'm in the process of making/upgrading a ChipAmp.
This integrated amp has 4 inputs, and 68W into 4 Ohms and 38W into 8 Ohms (LM3886).
I've spend quite a lot of time to get the best possible sound out of these chips, I've had help from others and read and tested so many ideas and configurations. it's definitely not according the datasheets provided by Texas Instruments but the sound is trully amazing.
The bass is so deep, so pure. The voices are so real and vivid. The guitars and drums are really standing in front of you.
It's just amazing. People owning 10k+ systems told me this simply sounds at least as good.
So that's pretty cool, and i'm pretty proud of the result.
But this is just the electrical part of the whole story.
I need a case around this amplifier... I'm a CNC machinist and therefore i'm not going to buy a $90,- case. I rather get a
$90,- $400,- chunk of aluminum to start with and mill my whole case out of it.
The raw material turned out to be way more expensive than expected!
I hope you guys (and girls for that matter) like to see the progress of this. I didn't came to brag here, just want to inspire others and hopefully you'll enjoy watching me make this thing
Wires! Ticking time bomb! This is what it looked like during my tests. How it still looks actually...
This is how it's going to look (hopefully)
Not so long ago something landed on my workbench:
Yup, a bit more than 300x400x100 MM
Need to be able to connect wires and cables somewhere:
Let's make some chips:
The material is just 3MM deep in these vices. It's amazing how rigid and strong it is! Thanks to the teeth we push into the material first.
First setup:
M3 thread inside, no tapping here, only thread milling! I really prefer that over tapping, much more reliable and very smooth thread.
Quickly had it on the 4th axis to make the threaded holes on the side
Final result:
Now i also need some brackets for two PCB's inside the case:
Well, That's it for now. In a few days i'll move along with other parts!
Hope you like to see this coming alive.
