Omega Race Power Supply Questions

<< < (2/3) > >>

Ken Layton:
Appears to be the complete AC power section of a Domino Man-ish vintage Midway video arcade game. There are TWO power transformers mounted on it. In the upper left corner of your picture is the filter capacitor bank which would have fed filtered raw DC to a power supply circuit board.

If you're dumb enough to do it with the thing plugged in, then you get what you deserve. If you're dumb enough to use a WET rag that will get water into everything, and then go and plug it in, you get what you deserve.

I bet you're unaware that people commonly put entire circuit boards in THE DISHWASHER to clean them?

Well, Ray, I'm glad you are giving the professional advice on this. Me? I'd scrap it and buy a power supply off the shelf. Nice, clean, and post "damp clothed" cleaned.

I'm not unaware that people use "THE DISHWASHER" to clean components (not sure why you keep CAPITALISING STUFF) -- so, put the PSU in the dishwasher! Ray said so!

I think you have to allow a little common sense when dealing with high voltage, and unless Charles Babbage built it, scrap it and use something reliable and new.

Me ... I have a wife and daughter, and I'd just but a new £10 PSU...

BTW. The PSU on my TFT (as I said) was unplugged and had not been plugged in for some while. Even so, I got a couple of jolts up my arm that convinced me that if I didn't know what I was doing, to stay well clear.

I would .... the key is in the drying.    :cheers:

I've thrown pcb's, monitor chassis, harnesses, joysticks, buttons, you name it and I have probably had one in the dishwasher before.
Just be sure to blow out any excess water trapped in the nooks and crannys and then throw it out in the sun for awhile.

I took that picture before I vacuumed it off with a brush attachment.  it actually looks 100x better without all the crud on it.

Ok, I knew the one in the lower right corner was some kind of power transformer.  I just wasn't sure exactly how to test it to determine exactly what it was.  The one on the right...I have no idea. 

This is from an Omega Race, so Ken was dead on. 

There's no 'on light' or anything like that, and it doesn't explode when I plug it in and hit the switch (this is wired into the cabs power switch with the switchin inline on the 110v line in which I believe goes to both the flourescent lights in the cab...which I haven't been able to get working either even after attempting to wire them directly to the power cord :).
