Progress, but only further in the weeds. I had to plug in the marquee connector to get power to the power supply. What, why?
This now gives me 12v and 5v on the power supply (but only 50 on the ac connectors on the power supply -- normal?).
But once I plug the pcb in, 5v on the power supply drops to .3v, and obviously .3v on the pcb.

If i am understanding correctly your power supply is wired to the marquee light. not exactly a bad thing but maybe its wired wrongly. By chance is the power supply wired in series with the marquee light or is it wired in parallel.
If the hot goes to hot and neutral goes to neutral then its probably in parallel. Another way to check is to remove the bulb out of the marquee, does the power supply still work? If it doesn't you need to fix the wiring. I have a hard time believing someone could make that mistake but i have seen dumber things.

The power stays on when the bulb is removed.

Update! Have a new power supply and getting good readings. But now I'm back to where I was, looking for another Gyruss pcb since this one seems a bit out of reach for what I can do for it. It gives garbled audio and picture -- haven't seen the picture but this is per previous owner, more on that in a sec. But, if I turn down one of the two sound pots on the pcb you can isolate one of the channels or layers of music and it sounds fine. Before I can see an image though I seem to be missing the video cable that runs from the monitor chassis to a wire a couple feet below. Basically it's the cable John unplugs at the 12:30 mark: https://www.youtube.com/watch?v=jISiTd9syNI&index=2&list=PLF6Omn2cXb7Z8ScA7Z4IV6XMb6nHd8X0NDoes anyone know if this is specific to the Gyruss or a standard arcade rgb cable with standard plugs? |

post a picture or video of the board activing up. getting a gyruss board is kind of difficult. especially a legit one. so fixing might be your only option as long as none of the customs went.
the cable is generic RGB input

One just came out of the woodwork this morning, fingers crossed on that.
In the meantime, I'm not finding an RGB cable easily, any suggestions?

its most likely just a 0.1" IDC header. i am pretty amazed that yours is missing since its kind of attached to the rest of the harness usually.

Since the previous owner probably used several of the old parts, I think this just went unnoticed. All of the rest of the harness seems intact. I found someone else's photo on KLOV which has the empty cable just like mine:  |

Well I'm pretty sure I know what connector that is. Just need to know what monitor you have. Also, what are your plans for the gurus pcb

Tis a Wells Gardner 4900.
The pcb came through from KLOV, should have it some time next week.

A few connectors and spools of wire, some pins and you can build you own RGB harness.

So the connector in the photo a few posts above looks like Molex. But the other end appears to be some other type of connector, which goes into the monitor chassis.   |

But the other end appears to be some other type of connector, which goes into the monitor chassis. The 3-wire connector with 2 wires in it (black/white) is your isolated AC voltage coming into the monitor. The 6-wire connector with 4 wires in it is for video (R-red, G-Green, B-Blue, and W-White for Sync). |
