Thank you very much..
It really seems to be a cool project. Just a few questions...

What FETs are used? Would a MPF102 works fine?
Is this only a guitar amp? Could I use it as a amp for my computer without major changes or would be better using another Preamp?
And.. if it is used for guitar, why 2 channels in the preamp?

Thank you, again.

hey.. the link is off. could someone upload it again? It seems like an interesting project...

Sorry that I revived the thread...

Yeah.. you've made up my mind... I started reading datasheets and everything and yeah.. it's a little too much for me now.. I'll start slowly =)

Thank you, one more time. See ya!

In The Schematics... You use Trimmers for four of the JFETs. What are you aiming for? I'm Interested in building it...

Bye

Wow... Thank you VERY much Fahey and teemuk.. I Couldn't expect better answers than yours :D

Since it's my first project, I won't try messing with thinks that can easily go wrong :D
The "humour value" was really in my mind, but it makes no sence if it doesn't satisfies it's main function, which is the audio part.
Well, I never looked for this type of enclosures here, where I live, but I'll see what I can get.

I'll take a look at those chips you've said Fahey. Just a few question. They are AmpOps... What should I do with them? A Basic buffer configuration? Follow datasheet sugestions? And, Do they do it all? Like, is it just "plug in" a preamp before them, the speaker after, and you're ready to go?

Thank you, again.

The Newcomer's Forum / Amp in a Computer Case?

Yeah... I've ripped apart almost everything from an old computer and ended up with a nice empty metal case...
I wondered, what now? Then, almost instantly, I thought that maybe I could build a Guitar Amp in that.

I'm an electronics student and I've built some stomp boxes and power suplies before, so I'm kinda familiar with everything. But never dealed with amplifiers... I wanted something that sound good but is still simple.. So I choosed to go with SS in istead of Tube.

The question is, is it possible? Like, Is there any way to fit the speaker and circuitry inside the case? Is there any problem in it being all metalic, acousticaly speaking.

Also, I haven't started my researchs yet, so I'm completely lost about what circuit to pick. If you guys have any sugestion for me to begin with. I was thinking in something like 30 Watts - 8 Ohm...

Thank You, Already
