Default Prototyping my 1st Hypex NC400

Here is my first Hypex NC400 attempt. This is not the final case just a quick way to get something together, with what I had, to try it out.

Default MHHA v4.0 and MKII Tripath TA2024

***
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.

Default 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?

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.

expl.


YJ 6N11 Tube headphone amplifier
YJ 6N11 Tube Headphone Amplifier New | eBay
MKll Tripath TA2024 Amplifier Board
MKLL Tripath TA2024 Amplifier Board 2X15WATT TA 2024 | 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
