I've checked all the common sources here in the US and the EL-30 (encapsulated) transformers don't seem to be stocked. The best source was a UK stocked part from Mouser, which takes the price from $12 to $32. Have I overlooked something?
I was trying to use the EL-30 for the form factor, but a small chassis mount toroidal may be my only option. If I were in the UK or EU I could get that EL-30 anywhere.
Thanks,
