up in smoke. no idea what went wrong. so long.

Eh, what's a couple of cheap parts in exchange for learning something? Cheap tuition. What was the project and what happened?

Is that a Dx copy ?

bryantramos79 · 24th April 2010, 03:07 AM

I plugged it in to the power supply and flipped the switch, and that's when it got interesting. I don't wish to take my curiosity for diy amps any further.

bryantramos79 · 24th April 2010, 03:09 AM

yes, it's an unauthorized copy, i didn't know it at the time i purchased the kit.

so ... how is this bad? looks like fun to me. we have an annual event here in california called "burning amp".

something was definitely not right. this is one place where you might get help.

You owe it to yourself,don,t give up.Everybody blows something up at one time or another, Don,t blame yourself and try to find out what went wrong.

Hang in there, Evette

So long indeed. So long since I first walked. And then I fell. So when I first fell, should I have given up walking?

That's quite impressive!
Looks like you let ALL the smoke out the 180 ohm resistor.

I'd guess the Vbe multiplier was wired up wrong. If it's just adjusted badly, you "only" blow up the output transistors.

Now clean it up and start over.

Do not ever! Start a new Amp without safety Resistors!
