ahh, nevermind. Turns out the coating of the table I was playing it on when it died tonight was conducting electricity a little bit causing a pretty big short in the amp... It works great as soon as I start playing it on my worktable. The old one still fails though.

I redid it, strictly according to the schematic. But after I play it a bit, it starts sounding muddy, and eventually dies on me. Lasts longer than 40 seconds at least this time Wonder what I'm doing wrong.

Is it ok to connect all the ground connections (the speaker, input jack) to the ground connection of the amp? Or is that what is killing it?

A resistance value of a resistor before the led is correct. I tried disconnecting the led and listen for it to die again, which it did. So, it has nothing to do with the led.. I´m coming slowly to the conclusion that I should just forego this creation of mine, and start over. I think there´s a short somewhere that I might have missed. (my soldering skills are oh so crappy)

I´ve gone over it.. Cant find a short, I´ve tested disconnecting everything and reconnecting.. Must be something I put on wrong..

When you have upright capacitors with two pins out the bottom (100uf and 220uf), the negative side is the one with arrows pointing down, right?

Here´s a video of how it behaves.. Gonna go over it with a spyglass, if there´s a short somewhere I´ll find it

I´m building a little gem amplifier. But not sure what I did wrong, I turn it on, and after 40 seconds or so it dies.. The speaker gives a whiny sound for half a second and the led goes dim. Does it mean the electricity isnt flowing correctly or something?
