You mean you added an output jack to the amp and it doesn't work?

Do you have some leads with alligator clips? These are the easiest way to test stuff before soldering. And they are cheap and last forever, if you don't have any you should get some.

I would start by just connecting the jack to the speaker wires to see if sound actually reaches the headphones. Normally the phones should be really loud with a direct connection like that.

Do you use a switched jack? these can be a bit tricky to figure out. If so, it could just be that the wires are on the wrong side of the switch. Flipping them would fix the problem. Normally the wire from the circuit board goes to the tip connector and the switch connector goes to the speaker. When not plugged, power flows from the tip to the switch to the speaker. When plugged-in, the speaker gets disconnected.

Pics so we can see... You really need a "switched" jack ... here's the best diagram I can find...

If you notice, the left and right output are disconnected when you plug in a headphone...   You should wire the output to both, then the output lead (one of them) to the speaker.

Stereo jack with a shunt if you want a headphone jack that cancels the speaker when the plug is engaged.

output wires to the speaker get disconnected when the plug is inserted.

Output speaker wire from amp to jack and then to speaker.

If the amp's output wires are only one hot and one ground(mono), you'll have to run 2 wires to the single hot(splitting the signal as a faux stereo).

Yeah, nah. Tried everything. Has anyone actually done this on one of cbgittys little artec amp boards???? Im goin crazy here.

Post some detailed pics of the wiring so we might see what's going on.

If you are using Artec amp boards, there should be a connection labeled JK+(output jack positive) or HP (headphones) on the circuit board.  Identify them and use John's diagram.

Hey ILL. Yeah I believe I've followed all advice and wiring diagrams, but I'm obviously still doing something wrong. When I get a minute I'll take a few pics to show what I'm doing. Cheers

Ok, I guess it would be a 1/8" headphone jack. But if you going 1/4" size then that has to be a stereo jack like the one in Paul's diagram.  May be some reverse wiring you'll have to do. Keep us posted.

I had some cheap jacks that didn't connect unless the plug was pulled back a little bit.  When the plug was all the way it connected both metal pieces to the same section of the jack.
