Will an upright Outrun amp work in a dedicated Turbo Outrun mini?

I'm trying to figure out if an upright Outrun amp will work in a dedicated Turbo Outrun mini.
Mine is missing, of course, in my Turbo Outrun mini. I can tell the connectors in the bottom of the cab fit the associated connection pins on the PCB. From the pictures, the wires in the connectors seem to go in different places. I can't find a manual for a Turbo Outrun mini (or otherwise). My guess is it should work, PCBs are expensive to design, and Turbo Outrun was often a conversion for the orginal Outrun.
 
Looking at a parts supplement for an upright Outrun Turbo doesn't show any separate opamp (although the thing is only a few pages long). it has the sound chips as IC's 14-19 on the CPU board. Are you sure it takes an external amp and doesn't have it built into the CPU?

That manual is for an OutRun-to-Turbo OutRun conversion kit. It assumes you have a complete OutRun, and the upgrade kit, which just included ROMs and an encrypted 68000 to swap out on the main PCB.

The OP is asking about a _dedicated_ Turbo OutRun. I haven't run across a manual for any variety of dedicated Turbo OutRun. (For all I know they were just standard OutRuns with the upgrade kit installed at the factory...)
 
Yep, dedicated mini. Right now, I'm thinking, I'll go for it and see what happens. There's a real lack of documentation for this game. Not even a good interior shot...

Yes, this should have had an amp PCB in the bottom. I can even make out the shadow of where it sat through the dust and screw holes. At least the connectors are still there.
 
You can always find your 12V power supply to the amp in your connectors, and make sure the pin you're about to plug that into connects to the proper leg of the amplifier IC. Sticking the 12V in the wrong place seems like the most potentially-destructive failure mode.

However, I like your logic that it's unlikely something new was designed, when one already existed. The OutRun amp is pretty simple. Just a 2-channel amplifier that runs off of 12VDC, with a muting line. If it weren't for the muting line, any old amplifer would work fine. Heck, I don't even know if the game uses the muting control... (I should check mine and find out)
 
I went ahead and e-mailed and PM'd anyone I could find on VAPS that has a Turbo Outrun mini and begged them to take a picture of the bottom of their cabinet to confirm that this is the right part. I even e-mailed Todd Tuckey (who I've heard collects minis) to try and sort this out.
 
Attached is how a regular OutRun amp is wired. If your dedicated Turbo OR has 3 connectors down there, with the proper number of pins, and the connectors keyed the same way... I'd plug & pray.

Wow, thanks DarrenF, that is what I need since it tells me exactly what each wire does. Looks like I'll need to swap some wires, but as along as I get the 12V and GND right, I should be good to go. I looked at the bottom of my cabinet, it looks like the larger connector has wires in different places. Take a look at my initial post:

I have a regular outrun mini! Would a picture of that cabinet floor help? PM me if it would in case I forget to check back in on this thread.
 
Done, and I have weak sounds and music now. When the volume pot is turned up, all output gets very distorted and scratchy. I reflowed all header and other suspected pins, but this did not help. My guess is a cap kit would help, but it may be the same afterwards. I may have to live with it. Better than nothing, I'm happy! This Outrun part is hard enough to find, it seems the one from the mini Turbo Outrun is different as it takes 48V AC from two separate lines and this one likes 12V DC from one line.
