Type R transformer wiring question | O Gauge Railroading On Line Forum

I recently picked up a Type R 110w transformer to run two independent loops. I want to run them with the low variable voltage range, meaning I need to use the B common terminal (with C & F). I would also like to use the fixed 14VAC output to power 022-style switches via the fixed voltage plug, but it looks like the fixed 14V uses the higher voltage A common terminal (with D). Voltage across B & D isn't stamped on the plate but reads about 7 or 8V. Is there way to wire this up to provide both low range and 14V fixed? I'm thinking no, and I'll need to phase in a 2nd transformer for the 14V, but wanted to verify. Thanks.

The table below shows the possible common ground arrangements for the R transformer: If using B as your common, I would use the 16V fixed on the E terminal for the O22 switches.

thx for the tip, I didn't think to use 16V. Certainly easier than adding a second transformer.
