240VAC to 12VAC Transformers

I’ve not tried one of these these so don’t take it as a recommendation, but something like this: https://www.jaycar.com.au/9v-ac-1-amp-plugpack/p/MP3027 might do the job if you don’t want to go the travel adaptor route.

I use one of these on my emonTX running the 3 phase sketch but don’t have access to a two channel scope to check the actual phase difference between the 240V and 9V sides.
If someone can suggest a method of comparing primary and secondary sides with a single channel scope I can certainly give it a go and report the results.
