I'll be going to the Big E show in Springfield in a couple of weeks and looking for a 12-14 vac source of power to run some accessories on my layout.
I was thinking about picking up a used Lionel Z or V transformer to fill the bill. I should be able to fit a dvm in my pocket. Other than the obvious, like a cracked or frayed cord, is there anything in particular that I should be looking for, or wary of, in these units ?
