I bought a couple of those 5V 6A power supplies (how can you lose at $2.95 a piece). Larry had mentioned a concern about the date code. While there is no date or manufacture's label on the PSU at all, the transformer and the power transistors have a date code of 88 and the info sheet that comes with it has a date of 87. I probably won't be using these with my MOTM, but they will be OK for some of my diy stuff.
