Mantabernd,
Awesome work! Very nicely done. Looks like a commercial product. How did you size the heatsink (what is dissipation req'd)? I am considering using a CPU heatsink with heatpipes.

Hello! Thanks! I did no calculation for the heatsink, I found three of these heatsinks (socket 423, pentium 4) in the thrash so I took them ;-)
In normal operation the heatsinks gets not really hot, a bit warm but not hot. At full output power you'll need a fan.
TI TPA3116D2 - Fantastic sounding amp!
This amp was made using the PCB provided by Dug (Thanks Dug!). It sounds really good, the best amp I now have. Amazing resolution, detail, and depth of bass.

This is a simple little amp based around the AMP6 kit I made for a friend a few years ago. For power we just used a Pyramid brand power supply for simplicity. The enclosure is a Hammond die cast if I remember right.
The vol pot is a Blue Velvet, input caps are Mundorf M-Cap, signal wire is Neotech and everything else is just quality generic parts. This was a fun little amp project.

5 x 5 cm class-d ... should be good for 150W
My new very small Class-D amp up and running.
So far just on +-30V to test it out.
It should be good for up to +-50V I think. Limiting factor will be heat from the 12V supply for the switches using a single FZT657 .... it has the ground plane as heatsink.
Self oscillating design, based on Op-275, MAX913, LM5104, IRFB5620 and a Ice Components 1D17A-220M coil.
At the moment runs at 229 kHz. I'm waiting for the right output cap, so I had to just use a small one I had on stock. Also waiting for decoupling capacitors; 1uF ceramic, so it is mounted completly without at the moment .... still looks good on the scope 🙂
Need some snubbers at the output fets as well ... and with my new Rigol 50MHz scope this should be easy to find the right components for.
Cute right? 😀

hi
i recently finished a sure ta2024 based amp. the psu and the amp are in a compact aluminium case.
i added 2 3300uf panasonic caps, 2 jantzen 2.2 uf input caps and an alps pot.
this is the first amp i made. what do you think?

Hello,
For those interrested by Hypex modules powered by connexelectronic SMPS, have a look to my blog : L'amplification audio en Classe D. (french language)

somehow the images in my post are broken and i cannot seem to edit my original post.
here are the pictures of my completed amp again:

posted in wrong forum (Chip amp) yesterday, repost it here hoping it's in the right place this time.
I'm new to the hobby and here's the very first try ...
got from ebay and combined things together, no mods no tweaks nothing changed to the circuits at all. Electronics exactly as is, quiet and sounds nice.

TAS5630 Amp
Hello,
this is my fist yet unfinished work.
It's a TAS5630b-amp in stereo mode, everything is hand soldered (the chip was a hell of a job to solder!).
It will be driven by the TI reference SMPS which was designed for exactly this amp.
I am going to expand my planned setup with a 4-channel TAS amp to make a full 6.1 surround system, which will be driven by a Hafler matrix surround decoder.
The question of the casing is still unsolved.
These are the pics of the board:
(Obviously I am unable to post pics linked from dropbox; at least this worked)
I hope I will be able to finish the whole system this year; it won't be easy, as I am 18 and just approaching my final exams.

I'd say you're off to fine start there young man. Excellent work! Be careful though.. This hobby is hazardous to your Paypal account. 🙂

Great work. This looks like it was a pre-fab kit - with everything included? Do you have a link you could share?
Rick
Many thanks for your kind words 😀
I know, I know ... that's one of the reasons my project doesn't evolve well (still, time is the main factor), as the overall project is a pretty big one, with all the stuff I have planned to include 😀
I'll try to list it all:
OPUS DAC
10-Band EQ
Preamps (still to be chosen and designed)
Hafler Matrix for Surround Decoding
4-channel TAS5630b-Amp Board
Various Bypass-Switches, Input and Output Selectors
SMPS PSU (TI Reference Design, being tailormade for the TAS5630 EVM; 150 at TI)
Headphone Amp
Casing the whole thing
And still I don't speak of the speakers ... But I guess those will be small yet sounding good. The amps will be a cruel overkill, but I guess that's better, regarding the THD+N ...

Everything not included,
- the two boards (preamp & amp) got from different places on eBay.

- power regulator from the obsoleted house security system
- hardware (case, screws, switches,...) from here and there
just housing them together under the same hood, the whole things not noisy at all & sounds surprising good.
Thanks for your kind words
