That's ugly.
It seams like a PCB made in the kitchen.
Where are the PSU caps?

i kind of get physically sick when i look at that GainCard PCB picture.


Peter's point to point layout is just so much more pleasing to the eye.


I think that the value in Peter's amp is the point to point wiring
and the layout... it's kind of Zen

Don't be too critical of the Gaincard construction chaps. I have an inkling into what is going on in there and there isn't really a way to make it pretty.

Let's face it, you don't admire the inside of an amp when you are listening to it. Or at least, you shouldn't prefer a neat and tidy layout to a better sounding, but 'messier' one!

Yep, Peter definitely wins in the naked amplifier beaty contest!

The PSU caps ? On the other side perhaps ??? Have a look at the second photo:

That is true. Remember that this sort of board has to be assembled by hand, there is no solder mask and silkscreening as it supposedly degrades the sound (and is not necessary for hand assembled board). So this is what you get, a functional piece of electronics.

Is that really the real deal? It looks like my first electronics project of when I was 13.
Somebody should point out to 47labs the existance of flux remover sprays. $4000 should at least pay for that. I bet it would be beneficial for the sound too.

I'm still full of respect for the amp that started revolution

I will concede that someone must have heard something in that design, with thin wires and crappy parts. Not to butter you up but your implementation is MUCH MORE professional.
