@H1000 posted:Perhaps you can locate a Williams or Atlas 80 watt transformer (they are identical except the label). I use one on my work bench and picked it up for $35 at a show. It's a classic pure wave transformer with Whistle & Bell.
80 watts should run your layout with two engines but maybe look at putting the accessories on a another transformer.
I think he's already decided he needs more than 80 watts. Why buy two transformers when one larger one with accessory outputs will do the trick?
