Darn it! Don't get old! The 7amp is.... W28-XQ1A-7 ...I use the 2amp on my test station.
I've used a bank of 4 with the ZW on my Christmas layout (on the floor, around the tree) forever... very high level of de-rails per day ...a lot of kids pass through during the holidays ...and, more than a few inebriated adults.
