@gunrunnerjohn posted:IMO the Williams transformer is nowhere near the quality of the MRC AH501 we're been talking about. For roughly the same $100 he gets a 130 watt transformer that outputs a pure sine wave and will work with an AC locomotive he puts on the tracks.
No disagreement there on comparing the two transformers. On another thread, @Mannyrock was discussing the purchase of WBB/Wms O27 FA-2 AAs for around $250 and then selling the dummy. Thought the sets might be a nice compromise in killing 2 birds with one stone. Also, since the OP said in another thread his layout is too small for a set of AAs and wants just a single O27 A unit, I figured an 80W transformer would be more than sufficient. That said, the MRC provides a lot of room for growth.
