It's a 2 player cabinet. It's awesome! But I can't find the volume control anywhere. Anyone know where it might be?

Did you look on the PCB? Sometimes there can be a volume pot on the board. I have seen some cabinets without volume controls though, they're a pain.

I've never owned my own arcade cabinet, so I wouldn't have a clue!
I'm incredibly jealous, that thing must be incredible!

It looks like TMNT (the first one) is a Jamma board. The pinout for Jamma says that the audio pins are on the connection, not the board.
You can see it on the pinout diagram here: http://image.pinout.net/pinout_3_pin_files/jamma-pinout.gif
If you're trying to use it in an MVS cab you need a converter, like this: http://bit.ly/jINR25 ... which wouldn't you know it has speaker output.
If you're using a Jamma cab, then the speaker output is going to be on the main board for the cab, not the game board.
Though, I've never messed with any of this, just an educated guess.

I didnt see it on the game board. My MS PacMan is like that but I didnt see a nob on the TMNT. I gotta stick my head in there again and do some hunting.

Don't Jamma cabs have a dedicated sound board? The audio stuff isn't going to be on the Jamma motherboard or the TMNT game board.

There's no such thing as a Jamma motherboard, that would simply just be the game PCB. The Mortal Kombat PCB listed in your link is a great example of this point, as MK (like many Midway titles) has it's own dedicated sound daughterboard. Without that sound daugterboard you would not get any audio from that PCB.
The majority of games do not have their own sound daughterboard though, and their volume is typically adjusted through a volume pot or slider wired to the cabinet, or even sometimes handled through the game's test mode function.

Gotcha. I don't actually have one ... and it's hard to find some better documented images on the net.
