Pumping sound from an Arcade Game thru a Sound System

Can it be done? Is there a way to add an RCA jack to the audio section of a classic arcade PCB? I am not an audiophile, so I am not sure what to wire to what if it is possible. Be gentle with me, it's my first time.

Definitely possible and pretty easy when the game uses a separate board for amplification. Just tap into the wires going to the sound board. Its basically what I did with my Pole Position to get rid of the ARIIs since it was already converted over to a switcher and the wiring was a hacked mess. I ran the wires that would normally go to the ARIIs to a couple little power amps.

**I'm no expert though so don't blame me when you blow something up. ;)
 
Though I've never done this I would have to say you can definitely do so. In most games I think I would tap in to the wires that run directly to the speakers. In games that have a separate amp board such as MCR games and such I would probably pull the sound before it reaches the amp. Sometimes running the amplified signal into a second amp can cause issues with sound quality.
 
There is a stereo inside my Sega Missile Command. I have not looked at how it was hooked up. I have no idea why it's in there.
 
Look at the purple and purple/white wires coming from j4 on the main pcb. (pin 1 and 3) This is one channel so you will only need a single rca cable/jack. Pin 1 is "positive" and pin 3 is "negative".

Here's the easy way. Make/buy a patch cord with alligator clips on one end and whatever connector you desire on the other end.

Connect the alligator clip end across the two speaker terminals on the cabinet speaker.

Now plug the other end into a "direct box" like this one and from there to your external sound system:

A "direct box" takes a speaker level signal, isolates it (for safety and hum elimination), and drops the signal level to a line level for feeding to other amplifiers. Some of my friends use the Direct Box to easily and safely patch their audio from 16mm movie projectors to external sound systems.

There are "passive" (no power needed to operate) and "active" (powered and amplified) types of direct boxes. A.R.T. seems to make the best of them and at reasonable prices too.

Cool. Is the one you linked to the correct one for my situation? If so, I will just click buy.
 
Here is the spec sheet straight from the manufacturer:

It will work for your application, but be advised the output connector is a male "XLR" type. So if you buy MCM's adapter # 27-4175 ($2.99) with it then it will give you an RCA jack connector. The direct box's input connector is a 1/4" jack.

The direct box is on sale too for $20.81! If ordering by web or phone, mention VIP/Source code 18SC6 to get the sale price.
 
We used to use something similar back in the day when we wanted to hook up an amp to a car stereo without rca jacks. Basically you hooked it into your high outputs and made them preamps. I still have one of those things around here somewhere.
 
can be done , you need to run an RCA jack to the positive side of the sound lead and to a ground . you will probably need to run the sound out to a pre amp then an an amp. just ensure the amp you run does not have a 48v phantom power, this can feed back thru some input channels and cook the audio on your board
