I found little gem stripboard layout.

Looking better stripboard layout for little gem.

I found at home tumbler with 3 pins, button switch with 2 pins and two 6.3mm jacks.
I wanna use tumbler 3rd leg or button for cutting of speaker when headphones jack is plugged in.
If in can use 6.3mm jack without switch it would be nice. Problem is I don't know how to do it.

I think this will help me a lot http://www.runoffgroove.com/phones.png

Can I use 4*on-on tumbler as on-off tumbler ?

I Soldered little gem and nothing happened only 9v battery got warmer.
I used that layout http://www.aronnelson.com/gallery/main.php/v/TheBigMan-Layouts/littlegem.gif.html
For wire on stripboard I used wire from components.

If the battery gets warm I'd say it's likely there's a short somewhere.

All components on stripboard are fine. Stripboard was cold.

If you have a multimeter, measure resistance between battery terminals (on the board, with the battery disconnected).

2m was 0,00
20m was 0,00
200m was 01,0

Just measured mine, got about 4kohm resistance.

I placed otherwise on stripboard as was in layout. Accidentally left side went right side  and right side went left.

Is that big problem. Can I fix it.

Components tends to need to be in the right place.

then the 386 chip pins will be reverse. also the transistor might be reversed -check the transistor pins..             
for the chip,  :-\  you COULD bend the pins so they stick up above the chip then solder it in flipped right to left 'upside down'... like...

i think everything else will be ok... right  to left...

didn't help. Battery gets only warmer.

What to Check, fix, correct and controll ?

You might find it quicker to build a new one.
Bringing you yesterday's technology tomorrow.

... and I reiterate this:

If the battery gets warm you do have a short circuit somewhere.

Check for solder bridges, touching components and anything else you can think of until you find it.
