Help me out with a little debugging

[smoguzbenjamin]

Hey all

Made an LM-386 preampp for bosting up my wireless. After a lot of work and patience I fired it up. Or not, it doesn't work. I checked the IC voltages, they look fine, I looke for soler bridges and I see none. I'm about to make an audio probe to trace the signal but still... Anyone have a suggestion in case I missed something?

Cheers

If the IC voltages look fine, then it's probably some sort of miswiring or solder bridge like you said.

All the audio probe will help you do is confirm that signal is hitting the chip and that it exits the chip. (Still valuable)

Figured it out. Signal went in the chip but not out. So I replaced the 386 and it works great now. Woohoo! Now I can play wireless without cranking my amp or mad buzzing.

Thanks aron
