I was happening to scroll on Craigslist and I seen guy giving away 3 makvision arcade monitors for free he said 2 work 1 doesn't. They came out of golden tee machines and I thought I could use one for my mame cab. I'm pretty novice with monitors but my stupid question is do these monitors require an isolation transformer? Or can I plug it into the wall with an adapter cord? I don't feel like blowing myself up so any help would be greatly appreciated.
