Need help identifying parts

[Popcorrin]

I have some parts from an old space invaders game and I was having trouble identifying the isolation transformer.  I have posted a pic below.  The first item in the pic I understand is the power supply board.  The second item in the pic is the monitor chassis and in the top right hand corner of that picture is what I thought may be the isolation transformer.  The 3rd item in the pic is what I originally thought was the isolation transformer but looking it over it has an assortment of voltages so I wasn't sure if it was a power supply and why would there need to be 2 power supplies?  Thanks in advance for any answers.

Pic 3 is your isolation transformer.

Well dude, an isolation transformer is a big heavy metal block. So picture #3 looks like it. But like you said yourself, in picture # 2 there appears to be something like that too.

Your best bet is to look at the wiring that comes from the monitor. Trace (follow) where those wires go to. There should be two or three wires that are the video signal, and then there should be two wires that are power and power ground. Try to find those leading to one of those transformer blocks.

Picture 3 is the isolation transformer, that transformer also puts out a bunch of other voltages as well (very common).

Are you trying to install a color monitor in a black and white space invaders?

Thanks for the responses.  The parts are leftover from a cabinet my brother-in-law mamed and I was going to sell them on ebay.
