There is a previous thread, but I could not find it.

For those who have the star wars hum. Replace the large "big blue" capacitor in the transformer/power block. These are avalaible from Bob Roberts.

Did so tonight and it worked like a charm. Thanks so much to those who helped with technical advice.

Again, it is good to know there is such a great knowledge base to draw from so us newbies can keep our games running.
 
Yeah, hear it time and time again... those caps pretty much will always need to be replaced.

We've got a System 1 cabinet (much newer than SW), and I was thinking it was going to need new blues... but it turned out there was just too much corrosion on the eyelets that go on the posts of the caps down there.

So, if you can't afford a new blue (whhhhhaaaaaaat?), then give the posts and eyelets and good cleaning and you might be able to squeeze a few more years out of the old ones.

Just tagging that in while the thread is fresh.

Congratz on getting rid of your hum. There is NOTHING in more aggravating than having a game that works 100% but hums all the time... just kills it for me.

This also good for getting a game up and going until you can get a full list together and buy all the parts at once. NOTHING is worse than having to make multiple orders and paying as much in shipping as you do in parts!

I think Bob Robert's web site also mentions putting another cap in parallel with the original big blue, as a debug method. You'd need a similar one, but if you were careful how you did it, you could probably run one in parallel for a while as well.
