So, this wants a proper build report! (It's on Open Discussion too: http://www.madbeanpedals.com/forum/index.php?topic=6957.0 (http://www.madbeanpedals.com/forum/index.php?topic=6957.0))
(http://i1023.photobucket.com/albums/af360/Ettore_M/Build%20Photos/1545768_10200919303337723_41343132_n_zpse9db38c2.jpg)
Finally and properly built it and it works! Sounds great! But you'll be the judges! ;)
Took me a year from design to a final build. But I truly worked on it approximately two months. Yeah, I know, unacceptable, but things happen in life, and we lose interest. :-\
Nevertheless, I never forget the idea and after the summer, I got to it again. As my other responsibilities allowed me, of course.
But now it's finally built and I'm really happy with it! :D
It's the first circuit I designed (if designing is glueing different pieces of circuitry together to make a finished product.. ::) )
Not yet labelled or knobbed, but the knobs are (from left to right): MASTER VOL - GAIN - BASS - MIDDLE - TREBLE.
Pretty complicated build, and I had several issues with it! NOISE was the most important. And it took me a lot time to understand that it is a grounding issue! Now I know! Always use STAR GROUNDING! Always...! ;D

And finally, the appropriate sound clip!

Hope you like it! ;)

P.S. Note that the schematic used for this is not the one on the first page on the other thread.
Great job here Hector! I listned through the soundclip and it sounds just clean and nice. Funny thing is that the two amps i have for bedroom purposes is the lil watter and the micro terror, the two who inspired you in the first place, right:) ...
How loud is it, if you compare to the mentioned ones? its hard to say by a soundclip how loud an amp really are. Or do you have a calculated/measured wattage on it?
Cheers!
That sounds rather excellent. 8)
It sounds really good. Post some pics when your done with the outside work. I hope my amp will sound as nice as this one; I want to start in January, if my friend has time for it.
Completely unrelated but I never thought about setting my special 6 on its face.
Great idea! I already stole it. Lol
What's the switch do?

Great work!
Sounds great! Be proud.
Nice job!
So the power amp is the TDA2040? I'm planning a build of this project http://diyguitarfreak.wordpress.com/2010/09/15/the-miniamp-2-0/ but but it would be interesting to look at doing a hybrid amp.
Also what song are you playing in the demo clip? I've heard it before...
So, that's quite a lot of feedback! :D
Thank you guys! I'm pretty proud of this one, and it sounds pretty damn good to my ears. ;)

Thanks, Bengt! Indeed, these two amps were the inspiration for this one. I saw Corey's (nzCdog) project and a friend's Micro Terror, and got me to design a DIY project with a little more wattage in it, just like the Micro Terror.
I have not built the Lil Watter and I don't own a Micro Terror, but from what I remember, it's really close to the Micro Terror in terms of loudness.
I cannot quite measure wattage at the moment as I need dummy loads (resistors) and I don't have them. But from the TDA's datasheet, it should be something like 10 watts with a 12V supply to an 8 ohm speaker. ;)

Haha! Yeah! It's pretty nice sitting on its face. But I just had it like that, because I stole its tube for the little one! ;D
I got it modded with the switch (and I modded it even more! 8) ), but from what I remember, it adds a cap to the circuit to cut some of the high frequencies.

Thanks! The power amp is the TDA2050. Very little differencies with the TDA2040. I don't quite remember but I think it's the output wattage. The 2050 is bigger, and as we all know bigger is better! ;D
And the song! My absolute favourite from John Mayer:
Hector
that clip sounds great
