Hello everyone, I have a cmoy amp I built a while back and it has worked great up till now. When I plug in my headphones the sound is muted until move the jack around inside the plug, which makes the sound go in and out. If I spin it around to just the right spot it will work but it's pretty annoying. Any ideas on how to fix this?

The jack is probably just wonky. I'd replace it...

It sounds like the jack is not connecting properly. Try applying a little bit of pressure from inside the amp onto the jacks terminals to tighten the fit. Be careful when doing this.
