I have a bally fireball classic and a williams gorgar. I would love to add a headphone jack on both machines for after hours game play. Is this even possible? I know that they have mono 1/8" jacks that shut down the speaker when you plug in headphones but how would I connect it? I don't need a volume control I have headphones that do that.
Thanks in advance

Im an electrician and have some soldering experience and nit shy to tackle a task. I just dont want to open a can of worms.

I getting the feeling that its not really worth doing. Especially after doing a little research I'm seeing the potential for a lot of headaches.

Thats true thedefog not needed so much with games without music. I just figured it would give my wife a break when my son and I play with the volume full blast. If you wouldn't mind sending me a drawing of that schematic that would be awesome. As long as it isn't too much trouble.

Sooooo whats the final verdict doctors? I have emailed the two major players making headphone jack kits and they all replied they have nothing for my machines. So this is the only option now.
