Default Ultra-small GC with LM1875

Here it is, another one, this time a tiny board with the two channels.
No box yet, when I get a transformer for it I'll decide if it will be separated or included in the amp.
Anyway, I plan to make it as small as I can.
It will have at least two line inputs and maby a headphone output, and I plan to use it for the computer.
Got to make some small speakers too...
Now the pictures, but don't laugh at the non-definitive (crappy) wires and plugs, because they are just for testing.

The board is 5x10cm and if I need I can cut 2 cm on the left.
Pentium cooler.
And, again, the 50k multi-turn pots.
0.0mv DC-offset.

This is part of my small bench, where I do the "small" things.
Even with my not-so-bad test speakers it plays very well indeed.
As a matter of fact, I'm getting to the conclusion that when you make a GC you always risk yourself making a high-end amp.

Thanks guys.
Raka, don't give me more ideas or this will end as a pocket amp.
But you'll have to walk by my side to transport the batteries.

Aha, the DUAL box.
It was removed from the PC I bought to make the case for my "PC Gainclone".
It's a switching PSU.
Imagine, almost everything inside that computer was made in Germany.
With some mods It's now another PSU for testing.
The amp has been playing with this one.
Not so silent as the yellow box one (or any conventional one), which is stabilized and I did it with two old and big transformers, but for tests it's ok.

The logo seems identical to the TT manufacturer

Yes, it's from them, Dual.
At the time (beginning of the 90s) they did several things.
Even Philips made PCs at that time, you know?
