Thumbs up PC Gainclone

At last, some pictures of my Gainclone.
No digital camera, just good old analogue, so it takes time...
The film ended before I could take a picture of the amp with cover on, so when I have it, I will post it here.
The box is from a Schneider 386SX/20 I bought for 17.50 Euros.
I'm impressed with the sound of this little amp, and very low noise.
And mow, some photos.

carlos, or you attach the the file with the browse button below when you post or like you did now, but that only works with online links, in other words weblinks

and when you attach files there is a maximum size, but dont now how much KB

Wink the little boards...

...bypassed my way, as I do with any op-amp.
And the 50k multi-turn pots.
That's why I have 0.0 mv DC offset.

Smile the back

And then the film ended...
I'll post a picture with cover on, as soon as I finish the film.

...and no comments, guys?
Is it so bad??!

I didn't finish the film yet, but let me tell you, so that you can imagine , the the cover is painted black.
The amp is all black, with a gorgeous blue led.
I'll post the photos as soon as I can.
Today I'm going to my father's house with my Gainclone, to test it with his Allison speakers (4 ohms).
He got really impressed at my house, with my Epos 11s.
If it plays well with his Allisons, he is going to make a Gainclone too.
Yes, my father is a (now retired) electronics technician.
40 years of electronics experience.
He was impressed how you can make an amp these days with so few parts.
And a good one.

It's great, i like the UTP wires . And it's not bad, they can't expect Peter Daniel finishes all the time .

Thanks, Taco.
The truth is that Peter Daniel's designs ashame us all.
He must have heavy machinery at home, or a very steady hand.
I would love to see Matttcattt's car amp, and Skinnyboy's water Gainclone.
Come on guys, where are you?
Skinnyboy, are you alive?
Beware, water and electricity can kill.

I have just ordered the parts for my car amp, they should arive thursday, and i should have some pictures of my progress by friday/saturday.

Your amp looks very good a strange alternative to p2p wireing IMHO.
