Hi, I feel like an idiot for the amount of time I have spent trying to get this clear, but I wanted to be sure I don't mess up any of my pedals. I have just bought a MJM Sixties Vibe which needs 18v and is 150ma. I have also just bought a CIOKS DC 8. Which two outlets do I plug the "stack flex type 1" into? I read that it needs to be into two isolated outlets...does that mean either jacks 5+6 or jacks 7+8 would be ok?
